I have recently found a website that is really interesting to add to my RSS feed. It is Ubuntu Geek and there, it would seem there is someone who has the time and inclination to play with all the pretty buttons in Ubuntu.
This site covers from things that are just broken and how to fix them to playing with new toys (software) as they come out. I'm impressed that they have managed to explain things quite well with the use of screenshots where critical steps are taken. As well, the articles are written with brevity so they aren't too much to digest and you can play further once there yourself.
Kudos to this site which is a neat reference for new users of Ubuntu.
