This concept has been pioneered by a few other sites, and your site (no offense) isn't very visually appealing. I'd suggest some fancy graphics for the front page (before people even register) showing the magical increase in likes your site offers, etc.
Once it gets redesigned it'll look better I'm sure, but for now it's....kinda standard.
Also, since I'm in a good mood...I'll proofread your title page, k?
