The recent Davis vs. Stanco war in FreeDevelopers has pushed my patience to a limit, and I feel very pessimistic about the future of the organisation. I simply cannot imagine how in earth they will manage to put thousand of developers to work under a democratic regime, when, being now just a handful of people, they are not able to put their egos away for the benefit of the community. Free software gets done by programming (like RMS did), not by spamming or, what is worse, telling blatant lies! What a pity.
