The number of developers who should have a personal blog and don’t is staggering. Not because they have nothing worth saying — most of them have been solving interesting problems for years — but because starting feels like a project in itself. Pick a platform, choose a domain, decide on a design, figure out what to write about, then actually write something good enough to publish. By the time you’ve made all those decisions, the motivation has evaporated. Let’s short-circuit that.

Why It Still Matters in the Age of Social Media

---

LinkedIn posts disappear in the feed. Twitter/X posts are ephemeral by design. A GitHub repository shows code but not thinking. A personal blog is the only owned, persistent, searchable record of how you think about your craft.

This matters for three concrete reasons:

Compound discoverability. A post you write today can rank in search results for years. That post on debugging a weird ActiveRecord behavior, the one you wrote in an afternoon — someone will find it at 11pm when they’re stuck with exactly that problem, and they’ll remember your name. That doesn’t happen with a LinkedIn update.

Proof of depth. A well-written technical post demonstrates more than a resume line. Anyone can write “proficient in Ruby” in a skill list. Writing a 1,500-word post that teaches someone something real about Ruby is proof, not a claim.

Ownership. Platforms change their algorithms, shut down, or become less relevant. Your domain, your content, your audience relationship — that persists regardless of which social network is ascendant this year.

The Platform Question (Answered Quickly)

---

This is where most developers get stuck longest. Here’s the honest guidance:

• Jekyll + GitHub Pages — free, developer-friendly, full control, good for anyone comfortable with Markdown and git. No database, no server costs.
• Ghost — clean, professional, better writing experience than Jekyll. $9/month for hosted, or self-host for free. Good middle ground.
• Hashnode — free, developer-focused, has a built-in audience for discovery. Good if you want reads early before your domain has authority.
• Medium — declining relevance for technical content, algorithmic discovery unpredictable. Skip for a primary blog.
• Substack — better for newsletters than for technical posts. Consider it as a complement, not a replacement.

The platform matters far less than starting. Pick the one with the lowest friction for you specifically and start. You can migrate later — and if your content is good, your audience comes with you.

On custom domains

Get one. yourname.dev or yourname.blog costs $10–15/year. Using a platform subdomain (username.hashnode.dev) signals that you’re not fully committed. A custom domain signals that you are. It also means your URLs are stable regardless of where the content is hosted.

What to Write: Solving the Blank Page Problem

---

The blank page is the real enemy, not the platform. Two frameworks that actually work:

The “I just figured this out” post. Something tripped you up this week. You spent two hours on it, found the answer, and thought “I wish someone had written this.” Write that post. It doesn’t need to be comprehensive. It needs to be accurate, specific, and useful to someone with exactly that problem. These posts are underrated because they feel too simple — they’re actually the most searchable and most appreciated.

The “here’s how I think about X” post. You have a mental model for something — database indexing, when to use a background job, how to structure a Rails service object — that you’ve explained successfully to three colleagues. Write it down. The act of writing forces you to sharpen it, and the post reaches people you’ll never meet.

Neither of these requires you to be an expert. They require you to know something useful and communicate it honestly.

Making It Look Good Without Spending Days on Design

---

Pick a clean, minimal theme and move on. The developer instinct is to tweak designs — don’t. Nobody reads a technical blog for the design. They read it for the content. A stock Jekyll theme or Ghost theme that’s clean and readable is fine. The content is the product.

The one design investment worth making: readable typography. Large enough font size (18px minimum for body text), good line height (1.6–1.7), decent line length (65–75 characters). These directly affect whether someone reads your post or bounces. Everything else is optional.

The Publishing Cadence That’s Actually Sustainable

---

One post per month is enough to build something real over time. That’s 12 posts in a year. If half of them are good, you have six genuinely useful posts that rank for something and attract readers indefinitely. That compounds.

Daily publishing sounds impressive. It’s also a path to burnout and quality decline. The internet doesn’t need more thin content that was written to maintain a streak. It needs more posts that actually help someone.

Write when you have something worth writing. Aim for once a month as a floor. If you miss a month, catch up — don’t quit.

Pro-Tip: Write the post before you build the blog. Seriously. Open a Google Doc right now and write the first post. If you can’t write one post before the blog exists, you won’t write one after. The blog is infrastructure for content you’ve already proven you can create. Reverse the order and both the blog and the writing are more likely to actually happen.

Promoting Without It Feeling Like Self-Promotion

---

Share your posts where the people with that specific problem hang out:

• The relevant subreddit (r/ruby, r/rails, r/webdev)
• Dev.to — cross-post with a canonical link to your domain
• LinkedIn — one post per article you’re proud of, with a short take on why it matters
• The community Slack or Discord for your stack
• Hacker News “Show HN” for genuinely interesting technical posts

The frame that makes this feel less like promotion: you’re not promoting yourself, you’re sharing a solution. Someone out there has exactly the problem you solved. Your job is to make sure they can find it. That’s useful, not self-promotional.

Conclusion

---

A personal blog is the highest-leverage career investment most developers aren’t making. Not because it builds a massive audience (it might, eventually), but because it creates a durable record of how you think, compounds in discoverability over time, and forces the kind of clarity that makes you better at your work. The bar to start is low. The friction is real but temporary. Write the first post before you build the blog. Start there.

FAQs

---

Q1: Do I need to write only about my primary tech stack?
No. Write about what you know and care about. Developers read broadly — a Ruby developer who writes occasionally about system design, career growth, or productivity isn’t confusing their audience. Just be clear about who each post is for.

Q2: How long should posts be?
Long enough to be useful, short enough that every paragraph earns its place. For technical posts: 800–1,500 words plus code is a natural range. For opinion pieces or career posts: 600–1,200 words. Don’t pad. Don’t cut substance to hit a word count. Let the content determine the length.

Q3: What if someone else has already written about my topic?
Write it anyway. Your explanation, your examples, your mental model might be clearer for a specific reader. Duplicate topics with better execution consistently outrank the originals. “Someone wrote about this already” is not a reason not to write.

Q4: Should I allow comments on my blog?
Optional, and more trouble than it’s worth for most blogs. Spam management, moderation overhead, the occasional hostile comment — weigh that against the conversations you’d actually have. Many developers skip comments and direct conversation to Twitter/X or email instead.

Q5: How do I know if my blog is working?
Search traffic growth over 6–12 months. Posts that rank for their target keywords. Occasional emails or replies from readers who found something useful. “Working” doesn’t mean viral — it means people who needed what you wrote are finding it. Check Google Search Console quarterly for search impressions and clicks.
