How did you meet people if you didn't go to the talks?
The more professionally organised ones don't tend to have that many stands, except for paying sponsors. I understand why they do that, but I think there's good value in "community stands" too.
I mean, the talks themselves are just "shut up and listen", right? Not too much socializing happening there. I think that revolving the entire conference around presentations is probably not always the best format.
There was a big space for vendors to have stalls but if you talked to them it was like talking to a sales person. Sometimes they had a tech-oriented sales person but it was still selling you their product.
