I’ll have to see if this is something I can easily pull stats on for our hosting.
Global stats, however, are easy to find. Check out StatCounter or CanIUse for example. According to CanIUse, IE has barely 2% usage. Chrome, between desktop and Android has over 50%.
We’re aware. We’ll be notifying customers who have reported IE11 issues to us previously a little closer to when we remove support. Also, note that removing support doesn’t mean we make Discourse stop working on those browsers. It simply means we’re not going to fix every bug we find that is specific to that browser.
