This kind of questions gets asked a lot here. The common response is "Fake it." Follow reddit's lead and generate content yourself until others catch on. You also might try mechanical turk, though I have no experience with this myself. Also, post a link. You'll get better advice if you supply more detail about your site or the actual site to look at.

The live site is not ready yet. Since, the problem seems to be more generic, I posted the question here.

If the same topic had been discussed in old threads, can you please share the link? I would be interested to read that discussion too!
