I think it should have no description at all. A layout similar to the newest member, premium member in the sidebar would fit much better.
Either way, for 0.8 ill create a little template function which lets your control every template tag´s legth. Be it title or description. Properbly in the form of
{$tag_name, length=150}
or
{$tag_name, 150}
Properbly the first, as it tells right off the bat what the number is doing
This is really something we need, cheers.
Ill play around with that tomorrow and post a pre 0.8 fix if you dont wish to wait
