I think wikis are a good learning source, it just depends on how you use them. Like some wikis I've seen are just like an online gaming site. Over all I think they are just like having your own website or blog. I've learned a lot about things from technology, but one thing I don't understand is how the computers get this information and so fast. Like for instance if the keyboard isn't hooked up to the computer how does it respond so fast. With just using wikis you can still learn a lot, by going to different wikis and different pages. They help you be more creative and help you do other things too. With wikis you can find cool information and write about and show to other people.
