What do you think of Craigslist www.craigslist.org? Like it or hate it?

I personally have not purchased anything listed on craigslist.com.....yet. I have been recently looking at the site because I bought a new house and am looking to furnish it cheap. Since yesterday I have found a brand new queen mattress set for $175- which is a steal. I had a neighbor who lived by craigslist and would always get free stuff people were giving away such as air conditioners and computers- it can come in very handy :)

I have often visited the site, but have not used for anything but browsing. I have nothing bad to say, since I haven't done anything there but browse, but it seems quite user-friendly.
