Blog skins

visited some of the classmates' blog and realised that 3 of us has similar blog skin! ha.. wonder why. I chosed this blog skin out of the rest is because of its good colour combination, its design (white dash as frame to frame up the post) which is very neat and green is good for your eyes! ha..

But i also realised that because i am using the Beta version, my blog looks a little different from the others who are using the same design. Both looks fine to me and i don't think it matters much. the only thing that i am worried about is the tool button that is on the right side of this blog. it seems that anyone visiting this blog can click on it and make changes to the side bar. Wonder why did blogger made it so?
