That would sort of be fun to throw together. Shouldn't take too much effort. Maybe I can host a test version on the 'perl-test' Heroku site and take down the extra copy of the Perl DiscApp site for a little bit.
Only issue would be getting people to actually add the above code to their page these days.. or just getting anyone really interested in joining. I'd image 'Skip 5' might just flip you right back to the same site you're on because there's only 5 sites in the list. haha
Have you paid Facebook before to post ads for you? I remember way back in the day paying a few bucks to 'promote' one of my band's pages. Did it actually work? I don't really know. Their metrics said it 'reached more people' but not really sure what that means or if anyone even cared or clicked on the links.
