Unpopular: consistency is overrated if you're consistent about nothing. 1 good post a week beats 7 empty ones. Quality of what you say beats cadence of saying nothing.

TestFlight tip: beta testers won't read the README. Put the one thing to try in the invite message. Activation jumped when I did.

What's the hardest part of shipping your first iOS app? Mine: App Review rejection #3. Not the code — the screenshot copy. Two tries to say what it did. #iosdev

You get a guaranteed $10k/mo product, but you can never post about building it — no founder brand, no day in the life. Take it? Mine: no. The brand is the moat.

Biggest mistake solo founders make on X: posting about tools instead of the thing they shipped with them. Tools are the means. The ship is the proof.

Unpopular: most growth threads are the same 3 tips rewritten. The engagement is the format, not the insight. Write the insight and the format follows.

Best channel you ever got a real user from? Mine: one genuine reply on a builder thread beat a week of scheduled posts. #buildinpublic

How I cut agent token cost ~4x: stopped re-summarizing the whole repo every call. Pass only the changed file + a 5-line context note. That's the whole trick.

The biggest myth in indie hacking: that a viral post builds a business. One post gets attention. Ten useful posts build the habit of showing up. The business is the habit.
