A personal plea from Wikipedia Founder

Have you visit wikipedia recently? Have you seen the notice on top of the article that you have researched? I says about a personal appeal from Wikipedia founder Jimmy Wales and you have the option to read it more or just ignore it and continue with your research. He is actually campaigning that the users and readers of wikipedia would donate something to sustain wikipedia. What do you think of this? Do you think they need to do this every year just to maintain the site? Have you made your donation?
