VC Investment Pattern Shifting?

I was checking out LinkSV today and noticed a new profile for http://www.milo.com/ another site to enable shoppers to research and buy locally.  That in and of itself was interesting but what was really interesting was the investors.  Traditionally in a $4.0m raise you would be looking at 1 or 2 VC's that would be doing the investment to ensure they have leverage / didn't dilute their equity position.  However, in this case there were over a dozen investors from the Wharton School, to Angels to standard VC's.  A fairly eclectic mix to what we would normally see in a social marketing venture.

So this begs the question, is there a new trend starting where the inside Angels are looking to get into bigger rounds with smaller chunks of capital replacing the traditional VC model?  Stay tuned this maybe worhth watching.
