Discovered this while working on the new RTE, which writes slightly more advanced (and supported) HTML into posts than the old RTE does:

We fully escape all of the content here via LJ::ehtml():

Maybe we should instead strip all tags and just show any textual content, unless that's an empty string, in which case, show the escaped HTML instead.

This is lowish priority, but something should be done before RTE 2.0 comes out of beta...suggestions welcome.
