Mid-season MVP for my online precalculus class is @CampuswireHQ. I used to be all aboard Team Slack for online courses, but CampusWire is IMO miles better for teaching. Students love it and are using it like gangbusters.

I just demoed @CampuswireHQ, a platform that aims "to bring course communication into the 21st century" by "streamlin[ing] Q&A, announcements and discussions". It feels like what LMSs could be if they were as good as @Twitter, @Dropbox, and their ilk. (link: https://campuswire.com) campuswire.com
