Who's Funding Del.icio.us?

Story Text:
Joshua Schachter says he's quitting his day job and comitting to del.icio.us, the social bookmarking service, full time.

After seeing my little project go from a small hobby to a large one and
then consume all my waking hours, I've decided to quit my job and work
on del.icio.us full time.
I've given a lot of thought to how to make this happen, and ultimately
decided that the best way forward is to take on some outside investment.

I'd be interested to know who's been throwing money at Del.icio.us - friends and family? Or something a bit jucier? With Yahoo's recent purchace of Flickr and the heavy interest in tag based app's it could be anyone's guess...
Congratulations and good luck Joshua...
