People on both sides would benefit from dialogue, so why isn't it happening already? The usual answer to "why doesn't X happen" is "because nobody's being paid to do it". That applies here, I think. Scientists don't engage end-users in dialogue because they're not rewarded for doing so, and there's an opportunity cost for doing that instead of something that will get you more funding. So I think the big question for tomorrow is: how do we pay for the dialogue? That, and: will my poster have a demo?
Unrelatedly, I really can't cope with non-tabbed browsing anymore. Even though I regard IE with great scorn, I'm glad the latest version copied it from Firefox. It lessens the annoyance of being stuck with it.
