The only criticism I have of Indie Hackers is that sometimes discussion can get a little spammy (lots of people looking for early adopters). Not every conversation is like that, but some posts are.
As someone building a startup on their own (full time) I've found Indie Hackers a really supportive community. The stories there are often relatable, and far less sensational than typically seen places like HN. If you're going through the daily grind of trying to grow a small business / startup then it's a good place to drop by every now and again to help stay sane.
They just care it provides the value they're looking for.
"How I [risked everything, failed big, quit job] and built a [moderately big number]/month business"
FWIW I run browserless, which is on IH, and has been growing pretty steadily: https://www.indiehackers.com/product/browserless/revenue
EDIT: Might also be cool to see growth in terms of customer growth vs MRR
Gotta say, your customer support is top notch. I asked a question on a Saturday evening and got a response 15 mins later. I was stunned!
Therefore I think that ranking and tracking what other people are shipping does nothing remotely useful. Maybe good for an entertainment, though.
