I know it's better for blogging, but Myspace is where all the fun is.  I know you don't have to write code here, and you can add tons of pictures, but there just isn't anything else here.  Myspace lets you comment on peoples pages, post bulletins everyone can see, arrange your top 8 friends in order of whatever, network with friends of friends easily, and it offers blogging and picture sharing (especially if you use photobucket).  So, why Xanga when you can Myspace?

Xanga is more streamlined.  Xanga was written by someone who actually knows how to develop a web-site (i.e. the code isn't ancient).  Xanga is safer.  Lots of people are on Xanga.

More people are on Myspace though, and Myspace offers more communication options, so it's always going to be more popular and more exciting.

But I like Xanga!  Grr.
