Just for balance, I went there, and it was pretty disappointing. I do love math and engineering, but it was very gimmicky, especially the panels. I tried striking up a few conversations, but people were really awkward and ran away. Also, generally as an event it was frustrating in many ways (for example, mobile internet is mostly down, and the agenda is not printed anywhere). But who wants to hear me complain.

The panels were IMO the least interesting part (unless you really like one of the people on a particular panel I guess). I spent almost the entire time walking around to booths asking the people who made things about their creations. That was gold.
