Right now, we have experience levels set at
The problem is that when submitting a session, it's pretty hard to gauge the precise experience level your session should be aiming for. And sometimes, during actual presentation, the audience requires a slightly different approach or the session covers multiple experience levels.
I think more sensible defaults would be :
a) Beginner to Intermediate
b) Intermediate to Advanced
Another conference used these experience levels and I would like to adopt them. :)
