Cal,
i think that we need some form of editor, but to allow html, would also assume you allow jscript, and if you have dealt with any other open source platforms, you know that there are those little b*st*rds, that have nothing better to do with their time, than to spend it trying to tear up stuff.

I think some form of tagging utilizing braces or brackets for customizing the profiles description would be a great asset, but at the same time, we have to consider security.
