I still keep reddit as a read-only resource, and yes, plenty of people still use it. There are niche communities that I sure do wish could hit a critical mass on the threadiverse, and the archive of advice and (mostly) human reviews of stuff are helpful.
That said, either it's reddit or it's me, but any community that's even slightly large seems to have a lost a little thoughtfulness and vibrancy. The takes are more boring, the jokes more repetitive, and I run across others' "goodbye overwrites" a lot more often than I thought I would, and generally in places where it seems like the original posts were genuine attempts to be helpful. Reddit is not gone, but it is reduced, and must eventually fade into the west.
