Wikipedia scares me! The volume of information available on it is massive, the people who contribute to it all seem to be a pretty authoritative sources and it pretty much covers anything under the sun.
Take today for example, I had lunch with James, a friend who works with a local telecoms provider. We ended up talking about HSDPA (High-Speed Download Packet Access), which is a 3G protocol for mobile phones and data communication. I didn’t feel I knew enough about the subject, so when I had a free minute, I popped onto Wikipedia to read up a bit about it. Bang! Here’s all you ever wanted to know about HSDPA, and then some. The article even goes into detail about how wide-spread the adoption of HSDPA around the world is. Wikipedia is quickly becoming one of my major sources of information!
