That is exactly why I consider fosdem as a very interesting conf: I am myself somewhat generalist, and attending a room almost "at random" leads to very interesting discoveries.
Last year I saw a talk about the internals of the jvm. It lead us to drastic performance improvements in the last year.
Two years ago, a talk about measuring time lead me to dive into theoritical physics in my spare time.
Alongside these discoveries, I will attend devrooms directly in line with our technological stack.
In short we will learn stuff, aligned with our core needs, learn to think outside the box and finally meet great people in a great city, Brussels.
I regret missing FOSDEM every year. Even when it was tiny. The announced schedule always has a lot of meat. Doesn't feel like filler, resumeware, fads, or corporate pap.
I imagine its like the difference between PAX and E3.
