I think I've mostly moved to Kagi, because someone needs to be incentiviced to actually focus on search, not ads. That said it's also good bang for buck in annual ultimate because you get access to multiple AI models.
That said, I so far continue to be mostly underwhelmed by AI except for basic starting points on scripts or for games like D&D.
Usenet is hurt a lot by takedown notices unfortunately. So lots of older popular stuff doesn't work. That said, things like Anime or something that isn't given a takedown seem to be on there about forever. The server speed is a benefit for sure.
