I've never been to JavaOne before, but this year I'm attending thanks to SourceBeat. I was planning on attending this conference as I do most - show up, look at the sessions and attend the ones that sound interesting. If it's anything like the MySQL Conference I attended in April, I won't be attending many. There were a lot of PHP and clustering sessions that just didn't interest me, so I only attended a few sessions each day. Compare that to NFJS, where there were many interesting sessions that same time and I hated choosing one over the other.
JavaOne is approaching fast and we'll all be there in 10 days. There seems to be a lot of folks planning what they're going to see each day. Is this a good idea, or can I get away with wingin' it? What about the parties - I've heard about them, but I have no idea what they entail? Are they corporate sponsored - or just a bunch of guys going out drinking together?
