Hi guys! Thanks for the responses so far. I know, I know, I'm asking a lot. A girl can dream, can't she?
So many people use portal/CMS programs such as vBportal and Nuke, which include the "Weblinks" directory feature. And already-existing hacks such as
MyBookmarks,
vBLinks and
vBDirectoryDrk-Lite (not sure about the name of the last one, sorry!) indicate that others know the joy of organizing links.

So I'm just hoping that somehow, somewhere, a lone hacker will arise from nowhere to create a truly robust version. And offer it to us for either free or a low amount (under $50). Yes, okay, I said I was spoiled.
Man, I thought this would be a popular hack idea ... shows you what I know! So is
no one else interested in such a product? Rats.
Anyway, thanks again for listening!
