I hadn't been to OpenWorld in a while until this year. Definitely a different tone than in years past. In the demo grounds, less "here are features we have in individual products", more "here are products built on top of those nifty features". Lots of demo booths from industry-specific acquisitions. Reminded me of IBM's SHARE conferences from the '90s, very customer focused.
Plus, Tom Kyte has a beard now. :-)
