I've been here for almost a full year, and I've made quite a few. Several I've texted, added on facebook, and we talk on other social networks and stuff. Even those who I only talk to on here, I have a pretty considerable amount, that I'll comment back and forth on their walls and message them.
Usually, I'm able to get along with all kinds of people, so even when there are cliques I'm able to fit in and I'm also a super-friendly people-person, so I always tend to make a LOT of friends REALLY quickly. I did notice what you mean though, when I first joined the site I noticed there were some tight groups of friends on here, so I had to kinda wriggle my way in
