Just about everyone knows about the biggies - Facebook and MySpace. But really, these are just the best known out of dozens and dozens of social networks. They are all over the place, often catering to very specific niches - dog owners, for example.

Could we, possibly, be taking it a little too far? Personally, I find myself limited largely to Facebook - where most of my friends are - though I do dabble a bit in LinkedIn and Flickr.

Some suggest that perhaps we’ve taken this thing to bizarre levels.Here’s an amusing article at PCMag.com, where writer Jennifer L. DeLeo offers her take on the 10 most absurd social networks.

Some that made her list: Geek Match Making,  RedKaraoke,  nclüdr, and Line for Heaven.

But my personal favorite has to be Hot Enough. It’s a social network set up for those who are, according to the site, above average.

Hollywood already does a good job of making us feel like we’re fat and old; we don’t need a site that rates us on whether we’re hot-or not. And yet, there is one, and it’s called HotEnough.org. In order to get your photo up on Hot Enough, you must send three photos, including one body shot. The dating site’s editors will go through a screening process, separating the attractive and athletic from the ugly and unhealthy. Anyone scoring between eight and 10 points is considered hot enough. There’s even a section for baby boomer hotties. Oy vey!
