The Stack Exchange Meta has the tag internet-explorer. The description is
Questions about site's functionality issues (bugs, incompatibilities, feature requests) in any version of Internet Explorer.
I reported a bug for Internet Explorer, which to my surprise was quickly downvoted. A user pointed me to this question which show which browsers are supported. He told me to "be aware of what is and isn't supported on the site".
Internet Explorer 11 was listed under supported browsers, but it had the following message:
•Compatibility mode should be disabled
•This browser is mostly supported on a "because it works" basis. Support may be dropped in the future, without notice, if new functionality is implemented that cannot be made to work in Internet Explorer 11
Are we now at the point where Internet Explorer 11 (the latest Internet Explorer version) is not supported on the SE sites? If so, I see no use for the internet-explorer tag as bugs should no longer be reported for it. The tag would violate "#2) Is the concept described even on-topic for the site?".
