Web 2.0 Tools

Lots of cool/interesting sites. I've surfed many on the list but craigslist is my favorite, if you're looking to sell,buy and trade something fast,cheap and locally click here. My only advice is to watch out for scams and fraud as rule #1 is to "deal locally", if you think an item's price is too good to be true, you guessed it. Also I like the fact that postings are free of charge and you can post anonymously.
