W5 Blog Topic : Can we trust Wikipedia?

I was quite skeptical before about trusting Wikipedia. The face that anyone can edit made me think of that we can't trust everyone's information and their knowledge. However, the more I use Wikipedia, the more I think Wikipedia is pretty reliable. Since I started eddting Wikipedia pretty much every week, someone wrote a message on my talk page about my editing. He kind of pointed out my mistakes which I had made while editing, but it was more like advices I would say. That was impressive because I did feel that Wikipedia is alive and people in it are constantly not only adding information, but also checking if the information is correct. They are voluntarily eager to do further to make Wikipedia better place such as giving an advice to a new Wikipedian. I am not sure how many percentage of information is correct in information is right now, but I can certainly say that it will be getting more and more. Also, what else could we use instead of Wikipedia which is changing itself? Would an encyclopedia which almost never changes or is hard to update enough to be an alternative to rely on?
