Just wanted to bring this to everyone's attention. StackExchange is in the early stages of replacing the current text editor for questions/answers with a new one that supports rich-text. The problem with this, as mentioned in an answer to the announcement, is it could make it more cumbersome to write Mathjax (the main way we present equations on this site).
Over on Physics Meta, they have started brainstorming potential ways that the editor could be improved to better handle Mathjax, since it is used on so many sites in the network. Take a look at these posts and provide comments/votes to show this is important and to express what you would like to see in a new text editor.
