Changes will be slow, but imho, definite. The oldies might have inertia but I think that people under the age of thirty (having grown up with arXiv and the like) much prefer open-access publishing. Cue for Max Planck's quote:

_"A scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die and a new generation grows up that is familiar with it."_

That said, we need to take initiative and step up to be the change we want to see.

TagTeam, being developed at Harvard by Peter Suber and co is one effort in that direction. https://osc.hul.harvard.edu/liblab/proj/enhanced-social-tagg... and https://github.com/berkmancenter/tagteam

I'm curious to see whether Mozilla Science Lab is taking any initiative in this regard; so far they've focused on other aspects.
