Stephen is going the distance
http://www.43things.com You already know about this site ;-)
http://www.latimes.com The Los Angeles Times is my hometown paper, but it represents much more than that in providing in-depth reporting and breaking stories that make national headlines. Obviously newspapers are suffering nowadays with reduced subscription/ad income and the staff has likewise been cut, but columnists like Steve Lopez (The writer behind the Soloist) that make this more than just a common newspaper.
http://www.gasbuddy.com This site allows you to find the lowest gas prices in the United States or Canada, and also allows me to preach the gospel of Electric Vehicles, that they are for real and you can buy one right now!
http://answers.yahoo.com This is the website to get stupid answers to stupid questions…or get good answers to good questions. More questions answered than any other site.
http://www.facebook.com Ok, choosing just facebook was a bit hard because obviously there are many competing social media sites which have advantages and disadvantages to them. but I prefer facebook because I can link to the groups I like, there is a more organized approached to maintaining contacts, groups, events, and so on, but there is a lot of room for improvement too!
