Robert,

This does not sound like Bruce at all. Bruce is a lot of things,
stubborn, sometimes temperamental, a lot of times like you... a hot head
but he does not take credit for other people's work in my experience.

I don't see this Robert. I don't see some secret hidden plan. I don't
see any cabal. I see a guy that has an idea, just like everyone else on
this list.

Even if there was, so what? IF EDB wants to have a secret plan to push a
lot of cool features to .Org, who cares? In the end, it all has to go
through peer review and the meritocracy anyway.
