In reply to Ryan Hellyer.

Respectfully that's a point we'll have to agree to disagree on. I've attended literally over 50 conferences in my career and full-on developer conferences have a very different vibe than conferences that mix developers and end-users, especially related to attendee experience.

Nothing wrong with end-users, nothing wrong with conferences that mix developers and end-users, but conferences that are developer-only have a value for developers that the mixed conferences can't match. IMHO, of course. :)
