Practically every college student takes mathematics or science courses at some point of their career and likely needs to access tutorials and other sites with mathematics formulas on the Web, so support for MathML would seem to be a priority for all browsers. This has been recognized by the developers at Firefox and Safari, both of which have supported MathML for some time. In the case of Safari, MathML support continues to be enhanced with each new release, while Firefox's support continues to set the highest standard. On the other hand, Chrome recently and inexplicably dropped it entirely, angering many in the education, mathematics and science communities, and now Explorer no longer allows the plugin that gave it MathML support. This leaves Firefox and Safari as the two platforms of choice for mathematics and science education on the Web, and many Web developers will be forced to direct IE and Chrome viewers of their pages to change browsers. (MathJax is not a usable workaround for developers in many cases as it is slow and, more seriously, asynchronous, and so will not work with the current architecture of many interactive pages, like tutorials, that need to display mathematics synchronously, or with pages whose Javascript code conflicts with the MathJax code.)

While I am happy to see that the Internet Explorer Team is considering including MathML support in a future release, I do hope that it recognizes the universality of mathematics on the Web and that MathML support becomes a priority.

Since the similar feedback https://connect.microsoft.com/IE/feedback/details/793339/ie11-feature-request-support-for-mathml was closed "by design" and http://connect.microsoft.com/IE/feedback/details/805029/please-support-the-mathplayer-plugin-in-ie-10-and-11 is not planned for the next release, I hope you'll at least consider integrating the CSS rules I proposed in https://connect.microsoft.com/IE/feedback/details/812595/add-some-css-rules-to-select-mathml-annotations-and-alttext in order to allow Web authors to provide fallback content.
