I recently found out that on mathoverflow.net, when keying in comments, pressing the return/enter key doesn't submit the comment; rather it does the most sensible thing, i.e., goes to the next line. I am aware of the ruckus this topic caused previously on this site (here and here). But now that mathoverflow.net has this "feature", would it be possible to incorporate this on math.stackexchange as well? If not, will this feature be incorporated in mathoverflow alone, when it gets upgraded to the "new" StackExchange platform.
Math.SE already has too much valuable content posted in comments. This is a problem for multiple reasons, I'll reiterate a few.
- Comments are difficult to search.
- Comments are difficult to port to another site. To display questions and answers, you only need to wrap them in
<div>and enable mathjax. Including comments on a page is a headache.
- Comments have low signal-to-noise ratio, contrary to the philosophy of the network.
- Back-and-forth discussion is what SE was made to avoid.
Adding formatting options for comments would encourage users to enter more information there.
In my opinion, comments already allow for too much formatting. I would rather see displayed formulas disabled there (converted automatically into inline), and the length of any MathJax code limited to 50 symbols or so.
