Like what inea said, go make a site on what you're interested in. Sure, making a site about something that's popular like the latest movie or a top anime would fetch you some traffic, but it wouldn't last long unless you actually like what you're doing. Find something you're comfortable with and something that you actually wouldn't mind maintaining in the long run. If you have some online friends, you could collaborate with them in making your site, because the more members you have on the site, the longer it could last too.
This is what I did with my own site; rounded up my friends, talked with them on what we wanted to do and did it.
That's pretty much it.
And, word of advice: Don't make a site for "Social Interaction". There's already sites like Facebook for that and I don't think people would join. Go with a specific thing (maybe a gaming site) and well, any site already includes the interaction aspect.
