It depends on your goals. If you are looking at authority at revenue sharing sites, Squidoo is still the first contender and InfoBarrel is second. But there are still few younger sites with a lot of potential, like Wizzley and Zujava, which are worth trying as well.
If you are looking at vibrant communities, major blogging sites like Blogspot or Wordpress can be very satisfactory. In this case don't forget
Facebook and G+. Of course none of these is a revenue sharing site, although I know few people who occasionally earn few cents on Blogspot.
In short: each has its pros and cons, but if I stay at your question without further explanation, Squidoo is the only contender.
