More OS projects need to be willing to stop adding features and just focus on the occasional bugfix or security update. Look at say GIMP. They have no market force demanding they add features every year in the way Adobe does. And while it's good and cool to add basic functionality like new image standards when they are published, many projects get stuck in this cycle of adding "stuff" for no reason.

(Back in the day that's why I liked Firebird^H^H^H^Hfox -- you could bolt on extensions if you wish, but the core product was light.)
