It's not an overwhelming lot, so I wouldn't expect you to find someone on there that you already know, but it has this sort of early internet forum charm, where you can easily get to know a handful of strangers and hop on there every now and then to talk to those.

Also, its community does very much consist out of the more technical crowd, with a focus on privacy and it also helps if you don't mind the occasional free software activist shouting about. That's just the group that's most likely to sign up to it, which can be a blessing as even with so few people, you always find someone to talk about tech stuff, but it can at times also get somewhat old...
