Del.icio.us apparently has taken a minority investment from a diverse group that includes Union Square Ventures, Amazon.com, Marc Andreessen, BV Capital, Esther Dyson, Seth Goldstein, Josh Koppelman, Howard Morgan, Tim O'Reilly, and Bob Young.
With so many big investors, one has to wonder what the valuation could be for this to be still a minority investment.

Update: I should have also cited Del.icio.us Founder Joshua Schachter's post on the delicious-discuss mailing list.
Update: Fred Wilson, a partner at Union Square Ventures, posts his thoughts on their investment.
