Some news about wikis and blogs

I found Ross Mayfield's reference about investments in Wiki- and Blog-mania quite interesting to note here for my future reference. I've just signed myself onto to Wikipedia yesterday, hope I'll be able to contribute something there. There's the Thai Wiki to keep an eye on. These past two days, I've also found Wiki's city, weblogs, slashdot (very interesting!), social networking, nanotechnology pages useful.
