Let the beatings commence, haha. j/k :)
I think it's fine to speak your mind btw. I just wish we had a better
way to speak our mind and somehow make more comprimises and/or engage
those who may have the wrong idea (say about the solver scheduler) and
instead engage them with some kind of 'something' to comprimise so that
both the disagreeing party and the people working on said scheduler come
to an agreement. Maybe that involves a lot of work (it does); maybe even
phone calls <-> between folks... but it seems like something we need to
work on to be a better and more accepting community.
