If you had asked me in 1999 if we would still be having discussions on the viability of Open Source business models in 2009, I would have looked at you incredulously. It seems like we're taking an awfully long time to learn the lessons of what works and what doesn't. Take, for example, the recent discussions around Open Core (see Andrew Lampitt's original post). I have to concur with Tarus Balog at OpenNMS when he says it's fauxpen source.
What we should be asking ourselves is not what the VC's want nor what makes us ideologically pure, but rather 'what's best for our respective communities?' If communities are indeed the lifeblood of Open Source projects, doesn't it make sound business sense to maximize community success?
