Why are so many people raining on Dave? The points he makes seem to make a lot of sense.
I'm pretty sure that an agenda that will attract the smartest angel investors for a meeting will stretch far beyond "collusion to bring valuations down".
The fact of the matter is that owning 1% of a company that exits for $100mm is far better than owning 10% of a bankrupt startup. These investors know this better than anyone and I'm pretty sure that increasing the size of the pie, attracting more startups, increasing the number of exit channels etc were the chief points of discussion and not "how do we make sure we own 10% instead of 5%".
Having said that, it's pretty much Dave's word against Mike's and I'll pitch my tent in the proven serial investor's camp any day.
