A blog i enjoy reading is Fred Wilson's A VC. He's a partner at Union Square Ventures, a NYC based early-stage VC firm. He's been blogging for a long time and his blog is overflowing with widgets and add-ons and tidbits, many of those from companies he's invested in (as I understand it). He also blogs a lot about music, and his indie rock tastes seem to intersect mine on many occasions. I haven't seen that often in the local VC community...
But his posts about VC are what keeps me coming back. This one, on what the Web 2.0 should mean for VCs, is well worth the read, especially for investment teams like ours, who are going back to early-stage investing after a few years of absence.
