Unfortunately, Om's post about Foo vs. Bar got Slashdotted, perpetuating the myth of conflict. This Slashdot comment put it nicely:
This is open source... its just a branch from the original idea, re-packaged by someone new for the problem that they want to solve.
Sure forks in the code/idea base aren't always good but I'm sure if Bar gets some good ideas that they will be incorporated back into the Foo release.
