As you have seen I also have little techie skills and only tried blogger but you can ban the comments from people who really liked your blue note site ...now look at my viagra blah blah and also the same with emails. This got really annoying at first and I think you can have it that all comments can be sent (ie approved) via you so in my European one party type of way I banned them all!
I have not tried the wordpress or my space.
I need something that I can edit quick and easy ( as I get the wrong facts or piccies) rather than a techie mate when they ain't busy so thats why I plumped for the blogger thing.
It depends how often you want it changed, how much info you have to put up and what types...ie text and piccies or videos and music. I have only ventured on the first 2 as I have not got the first clue about sound and vision
What do other people use?
The main catch like all IT is to keep it upto date and visually appealing I guess.
