Nice list.. I agree with those. However I do have that pop-alert.
I choose not to overlay my profile cos I noticed it freezes on most computers.
And most people visit net cafes, most net cafe pc's are badly maintained.
These occurance (freezing) annoys much of your visitors.
Instead of putting both mp3s and videos together, I prefer to choose one.
Either mp3 or video. I don't like hearing too many things on my profile.
I also don't accept flash testi's with annoying music/sounds.
It might sound rude, but I talk to my friends about why I didn't approve it.
It's good to atleast tell them why you didn't accept it.
Or if you want to accept it, try accepting the profile on a later date.
That would put the testi on the back part of your testimonials hehe.
I choose not to put too many designs on my page, they look cluttery.
I like it simple, but unique. Clean and easy to navigate. That's it.
