I am actively using Indie Hackers. It is a very supporting and nice community. It is very motivating for entrepreneurs. If you are building a product, you have direct access to a ton of like-minded founders who can tell you about their journey. It's for entrepreneurs.
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.
