Having gone last year, which I enjoyed, I can say it does not actually offer much bang for the buck per se. You listen to a lot of speakers/ presentations and the portfolio showings/contestant stuff.
There were apparently less presenters than last year and mostly the same ones, minus...
I considered it (last year) as entertainment and not so much educational.
The benefit was to "feel" that silver based photography would be around for some time.
I think lack of advertising hurt it severely, than again, I'm not sure what it is they were selling. Maybe they weren't either..
Hopefully someone who presented or represented will chime in eventually.
