I don't have an answer to this question, but it gave me an idea. Rather than look to Jive for recommendations, what if the community made recommendations?
Specifically, let's say each session at Jive World were listed as an idea so people could vote it up or down based on how appealing it is to them, and they could add comments, too, to give more context to what they think. As a Jive speaker, I'd find that kind of input in advance extremely valuable.
As an attendee, I'd leverage the wisdom of the crowd and take it into account in selecting the sessions I attend. And I'd know which ones to arrive at early so I make sure I get a seat before it fills up!
This is actually a great idea. It would definitely help the speakers see what the going-in expectations are as it relates to the description provided. Additionally, the Idea's inputs could be used to compare to results of an immediate exit poll/survey (electronically of course) performed at the conclusion of each track session.
So what say the Jive conference organizers & strategists?
