Wikis aren't all that reliable if you're going to them in searching for information on something.  Wikis are definitely not something that should be used as a source for a paper, as anyone can join a wiki website and edit the content.  For the most part the information is mostly accurate, but there are people who for whatever reason put up false information in an effort to sabotage the information on the page or just because they don't know it's inaccurate.  Although I know Wikipedia isn't 100% true, I sometimes find myself going to the site to just get a general idea of what something is if it's something I had never heard of before.  In fact, if I just google something, a lot of the time a Wikipedia result is one of the first few pages in the search results.

The blog section was interesting to read since I am doing one for my project.  There are so many different kinds of blogs out there on the net – it blew my mind that there are over 10,000 new blogs created every day!  An interesting thing Sunstein points about blogs is that there is no prepublication peer review...although at the end of the blog there is a comments section.  This is where people can post and alert the blogger to any kind of errors they noticed or just about anything they want.  Sunstein said it best when he said blogs "...offer a stunningly diverse range of claims, perspectives, rants, insights, lies, facts, falsehood, sense and nonsense."
