Currently, questions with TeX markup in title are excluded from Hot Network Questions. On one hand, this removes the concern about users of other SE sites seeing unparsed markup in the sidebar. On the other hand, this raises the concern about users of other SE missing out on accessible Math.SE posts they would be interested in. I think this aspect should be considered when editing questions that can be useful to a broader audience, especially when the benefit of markup is purely cosmetic.

Concrete example: an experienced user slightly edited a question title from

can someone explain how tanx/secx = sinx?

to

Can someone explain how tan x / sec x = sin x?

but refrained from introducing TeX markup. This allowed the question to stay in Hot Questions and amass 1300+ views in less than one day. But when another user edited the title to

Can someone explain how $\frac{\tan x}{\sec x}=\sin x$

that was the end of the question's popularity: it was immediately removed from the sidebars around the network.
