I couldn't agree more...
If you're trying to select speakers...I'd be more interested in the topics than in the presenter. What would get me interested? Some serious coverage of the PixInsight platform would get my attention. In terms of people: Juan Conejero, Manuel Jimenez, Vicent Peris, Carlos Milovic, Rogelio Bernal Andreo, Steve Leshin.
Juan Conejero is a walking encyclopedia of image processing knowledge and he communicates his knowledge extremely well - at least in a written format. His support posts over in the PixInsight forum are typically mini-lessons all by themself and do a good job of putting complex processing concepts into laymen's terms.
I wouldn't mind seeing some presentations on using our equipment for stuff other than pretty pictures. Lowell Observatory has a bunch of people who can talk on pro-am collaboration. Tim Puckett of Apogee is extremely personable and has some knowledge in this area as well.
I'd be really interested in a speaker who's doing some great astrophotography with mortal equipment. $250,000 of gear and a mountain top location and I expect you to turn out APOD quality work every time you boot up the laptop. Show me a guy who's doing it on a blue collar budget with say....less than $10k of equipment.
In the same sort of vein....find me a speaker that can talk about setting up a remote site....without having to spend huge cash to do it. Show me how to put my $20k imaging rig somewhere dark and remote in a permanent arrangement that doesn't require me to break open the kids college funds to pay for it.
What would I not be interested in? Going to see a speaker who's going to talk about all the same curves, high pass filters, clipping masks and other stuff that I can get from dozens of online tutorials.
That's just my rapidly depreciating 2 cents....
