Only when done right. When low-effort posting of said build in public data is done it just looks spammy. It's the IndieHackers problem, that whole site is full of people going "I agree, I did that with <mysite>.com"
I remember posts routinely getting dozens of comments and responses. Nowadays, if a post gets low double digit comments, it is doing very well. Sad, imho.
There’s also no effort to tone down excessive self-promotion posts and posts that instead of kindle discussion on-site, they link out to third party sites.
Sad indeed.
