They 'could' allow CSS, so you would get the same thing as back in MySpace days. Every users post looks different, sometimes nauseating. I am not sure how I feel about this to be honest. Whilst the idea may sound like a good idea, at first, in the end, the place becomes so obscenely glitter GIF'd out and LOL CAT'd out that it could drive you insane.
I am going to be sitting on the fence on this one, for now. Until someone comes up with an elegant way to implement things.
One thought, would be to allow users to turn on/off customisation, as they so please. Perhaps that could be an idea.
In the meantime, have a fancy schmancy lil LOL cube...
