Knowmia isn't the only product that TechSmith is shuttering. They are also ending support for Snagit for Chrome and removing ScreenChomp from the App store this store. Snagit for Chrome provided a nice way to create screen capture images and videos on a Chromebook. ScreenChomp was a nice, free iPad app for creating screencast videos.
TechSmith says they're ending these popular services so that they can focus on Snagit for desktop and Camtasia which both cost a minimum of $23.66 even with an educational discount.
I'll be sharing a list of alternatives to TechSmith's products soon.
Update: I just heard from TechSmith that they are going to continue support for Screencast.com and Coach's Eye, and Jing. So they're closing half of their free products.
