Jason Calcanis is a man at war! He is angry about angel groups who charge entrepreneurs money, sometimes a LOT of money to pitch to their groups.  He's received a ton of feedback to his original post , much of it summarized here.  The fees being asked are in the thousands of dollars, sometimes exceeding $10k.  Brad Feld, of Feld Thoughts (a VC who is still a good guy), responds here with the colorfully named "An Angel Investor Group Move that Makes me Vomit"

In short, Jason names names and exposes bad practices and bad actors.  Entrepreneurs, forewarned is indeed forearmed.  He is getting feedback from entrepreneurs who have run this gauntlet and exposing the whole sorry sector.

To borrow a phrase, if you, an entrepreneur, are asked to pay a material fee to pitch to group of angel investors, "JUST SAY NO".
