Four Web 2.0 Sites to Know for 2008

Pownce
Pownce recently came out of beta and is now officially public. This is one of my favorite Web 2.0 sites. Read more about Pownce over at Webware.

Ma.gnolia
Ma.gnolia is an online bookmarking service similar to Digg, Del.icio.us, and StumbleUpon. In comparison to those sites, I would say Ma.gnolia is of a higher quality. There is less spam, more relevant links, and a great community. For a little more about Ma.gnolia, here is an excerpt from their site:

With Ma.gnolia, that’s really all the work you have to do. Finding by tags makes organizing bookmarks a thing of the past. Since it’s a website, your Ma.gnolia bookmark collection can be reached by you and your friends from anywhere, any time. And don’t worry about web pages disappearing from your searches or even the web, as we make a saved copy of each page you bookmark where websites allow us to.

StumbleUpon
StumbleUpon is the new Digg of online bookmarking. Now, instead of Digging sites, many people StumbleUpon them. At the moment, this is probably the most popular social bookmarking site on the web. They have more than 4 million members. Definitely a site worth checking out.

Jaiku
Although there has been a bit of discontent with Jaiku lately, I don't think people should totally forget about Jaiku. I completely understand, and agree, with people moving to other sites like Twitter, for now. But, if Jaiku really does make major improvements, as they've promised, I think they'll be back on track to compete with the best. Hopefully, Google will pull through on this project. There is so much potential for Jaiku, especially if it is integrated with Google's other world-class applications.
