Wiki Web 2.0

Throughout this Web 2.0 course I have been wandering around in a maze; now and then finding a straight pathway only to run into a dead end. It is assumed that everyone knows how to do what are supposedly basic things like cutting and pasting a permalink. I need help with everything; nothing is easy, and I may not remember how to do what I did again! I am really not interested in blogs or wikis; everyone has something to say and everyone thinks what they have to say is most important.
