If you are looking for inspiration or case studies, try Starter Story. They pretty much picked up where Indiehackers left off.
I do agree that the past several months, and the past several podcast episodes have been less than exciting and inspirational, but I wonder if the reason has anything to do with this decision. It may be that there were changes happening behind the scenes and Courtland and Channing were getting bored and that affected their enthusiasm. That could be why they decided to leave and rekindle that Indie spark.
Either way, I never thought the value of IndeiHackers was in the forum post - comments sometimes maybe- but rather in the podcasts and interviews as these told the stories of starters and how they built their companies. To me the forum was just a way to keep traffic around engaged between episodes of the podcast.
Indie Hackers is hit or miss. Occasionally, you stumble upon a great nugget, you find outstanding help from community members.
Typically, you get a lofty influence post with no value.
I am still a member. Semi-active. But not very involved.
Looking forward to the future, though! With reclaimed freedom, I would love to see it flourish again.
