Well, we're drifting off-topic here (well, Dan and I are, anyway), but it wouldn't hurt if Great Bridge were to start recieving a flood of e-mails screaming for outer joins, lamenting the fact that InterBase appears more and more attractive every day (doesn't hurt to exaggerate slightly), etc etc.
They claim to know the importance of outer joins, based on survey work they did.
I know Jan Wieck knows the importance, and he's working for Great Bridge, my guess is that he'll pick it up himself if no one else does.
