Agreed.

But here's a thought: we already use XP to regulate voting rights, home node usage, and so on, why not tie() certains classes of tags to XP as well.

That way, only the people with the most to lose have the ability to write their potentially evil code.

Maybe <script language="javascript"> and javascript: tags are filtered when the user is less than a... monk?

In response to other suggestions, I think that the peer review/approval system is tough because it only pushes more work on to the senior monks (who, presumably, have a good deal else to do with their time).
