A problem is that it is not a semantically correct use.
At the moment the formatting used by SE on this site for block-quotes is such that optically its usage for emphasis makes sense. Yet, this could change at any point in time. Moreover, already now I feel it is not really the case on the mobile site.
In addition, imagine some machine reads the site to ...
No. SE mobile app doesn't have many features that the mobile/desktop web already has. Personally (though many have voiced the same opinion), the only useful thing is its push notification.
You can see the most-voted, open feature requests for Android SE app on main meta, like:

MathJax's HTML-CSS output tries to use locally installed fonts, when possible, and it looks for two local fonts: the MathJax TeX fonts, and the STIX fonts. If neither is found, then web-based fonts are used (usually the MathJax TeX fonts).
In your case, your earlier image shows the MathJax TeX fonts, so that is using the MathJax TeX web fonts. The second ...
Yes, a typed-in at-notification will ping. You could also type it out on your laptop. I frequently do this. (Why do you think it does not?)
The feature you describe is only there to ease the input of a notifying string. For the notification it is ultimately irrelevant how the string came into the input box (auto-complete, typed-in, copy-paste, it does not ...
On Android Stackexchange app there is no apparent way to delete your own Question (even if there are no Answers) or to delete your own Answer. (It is possible to delete ones own Comments, by touching it to select it and then touching the Trash Can icon at top). On the other hand, there is a "..." (more) link below the Question which contains an option to ...
I found that preview is available on the full site, which can be accessed from a mobile device by tapping "full site" link in the footer.
This is a test to see if the full site works ...
Actually this is cool! Thanks, I'll remember to switch sites ftom now on. Thanks everyone!
