I've been toying with signing up on myspace, but I'm one of those privacy freaks. How private can you make it? I just don't want my email address and stuff like that out there for the world to see. 
I haven't read this whole thread, because I stopped when I read this. I was one of those people who was never going to have one of those blog things, but then someone told Jamie about Yahoo 360 and we took a look at that. You get your own page, can link it to other blogs, if you want, through "a feed", so you can have all your stuff in one place. But, the really nice thing about it is, you have all the control over who sees what on your page. Like you can make your e-mail private but your age public, if you like. You customise it. You can have it so just your friends can see your photos or have it so everyone can. You can have some albums which only friends see, some where friends of friends can see them, soe totally private, some public. It's up to you, so that makes it nice. You have privacy control on each section.
Anyway, I started a thread about Yahoo 360. I haven't had any replies as of yet. I had asked if anyone else was on it and what they thought of it. So, perhaps no one from here has tried it. Don't know. But, I thought when I saw the thing on privacy, I would give that bit of info in this thread, as well.
