I thought lots of people who don't have booths pay for a ticket with the express purpose of networking. I didn't think you could get in without paying $1.5-$3k for a ticket? Maybe I'm wrong but that was the impression I had.
How is paying to go to a conference where you can network (or present, if you are lucky) with the whos-who of tech, versus for the opportunity to pitch to 1 single angel group/firm ? Not even remotely connected - absurd to even think so.
On top of that the amounts of money seem to differ by at least an order of magnitude.
