Not hack in the sense of trying to exploit or expose an exploit in the myspace script -- that's been done. This is more hack in the sense of a workaround -- specifically, working around the awkwardness of myspace's html code.
The Myspace Open Source Hack Initiative, moshi, will track the evolution of the myspace civilized and provide a repository for the myspace civilized stylesheets.
The Google Project page has been set up:
moshi project page (code.google.com)
Files and screenshots will be uploaded within the next week.
It's amazing, I just stumbled on your blog and we seem to be working on the same project at the same time.
I also was asked to whip a myspace profile into shape for a friend and found the profile code both maddening and intriguing.
You can see the results of my work for him here: http://myspace.com/creamapparel
Also I've worked up a deconstructed/guide profile here: http://myspace.com/layout_beta that i just finished on friday
feel free to get in touch through myspace or my site.
