Looks good to me, although I personally would change
"and there is a bot maintained by Troy Henderson that allows real-time testing of LaTeX, MetaPost, and ConTeXt code."
to
"and there is a bot maintained by Troy Henderson that allows real-time testing of MetaPost and ConTeXt code."
Even though the former is correct, I guess LaTeX is a little off-topic. Here are examples of how to use each bot in case you want to include them on the wiki:
!l Here is my formula \[\int_a^b f(x)\,dx = F(b)-F(a)\]
!m draw fullcircle scaled 72;
!c Here is my formula \startformula \int_a^b f(x)\,dx = F(b)-F(a) \stopformula
Clearly, !l is the LaTeX bot, !m is the MetaPost bot, and !c is the ConTeXt bot.
