Social Media Connections

I invite everyone to follow me on Mastodon. Please don’t expect me to automatically follow back, or if I follow you to keep following forever; I optimize my social feeds to provide a personally useful blend of information, and there are many interesting people I do not follow. If you are a student in one of my classes, I will not follow you until the class is over.

I also welcome LinkedIn connections. If you want to connect with me on LinkedIn, please say something personalized (even if it is just a brief sentence); if we have met in person or communicated on other forums, mentioning those is good.
