Db Expo in 1991 - I was developing a project time-tracking system in Paradox and feeling like I should be moving over toward that new Client Server stuff, with Oracle and SqlWindows (Gupta). Went to Db Expo and everyone (esp Michael Stonebraker) was talking about how none of this stuff actually worked yet.
- went again when it overlapped with NetGravity conference I was speaking at (re Medscape Ad Serving). Didn't find it nearly as useful this time.

current attitude: if you're ripe for a significant change in perspective, and you go to the right conference for that change, then you can get great value. And sometimes just having a few days away from office/home, while having some bits of intellectual stimulating, can have benefits. But it's a pretty inefficient way to gain incremental knowledge, esp in the days of blogs and online forums.
