There are enough people here to have some nice chats, and to consume some content (depending on your interests). It still hasn't reached critical mass if you're looking for a 1-to-1 Reddit replacement. If your main interests are news/politics (with a US slant), tech and gaming you're probably alright here.
Niche communities struggle if they exist at all and even those that actually are represented here are mostly barren. Sports coverage is also pretty poor.
