I think getting people to talk to you has a lot to do with how you're playing the character. First off, new people do need to try to fit in. Just like in real life, sit back a little and see what's happening. Utilize the journal comments and random community to get your presence known. If they get interesting comments or read fun randoms, they're more likely to seek you out themselves or know who you are from whatever you said. You won't have instant friends unless you joined for or with them. Patience!
