10 Websites to Watch in 2011

There are more than a trillion URLs in Google’s index. Yes, that’s a one with twelve zeros after it. And Google crossed that milestone two and a half years ago. With so many sites on the web in 2011, how do you know which to pay attention to?

Mashable’s editors haven’t quite visited a trillion pages, but we’ve checked out a lot in the past year, and we’ve compiled a list of 10 websites we think are poised to have big years in 2011. Some of these are relatively new sites we think will catch the mainstream’s attention next year and others are older sites that we think will finally hit the big time in 2011.
