I absolutely agree that clear titles are a must, and have edited them myself for clarity...though I was once reluctant to do so, I am no longer. You have editing privileges; go forth and edit :)
[...] I don't like editing people's titles, generally, but this one
(and some other from the same author) just really rubbed me the wrong
way. How am I supposed to know what the question is about from his
titles? ~ Shokhet, Jan 14 '15, in V'dibarta Bam
@Shokhet I actually think titles are one of the more important things
to edit -- they're what's on the front page, so if they're unclear or
incomprehensible or thoroughly ungrammatical or whatever, and you can
figure out what the fix is, please do it. ~Monica Cellio, Jan 14

Besides for the issue of the front page, mentioned by Monica Cellio, above; there's also the issue of searching for questions. I'll often search questions here for information, or to make sure that a question I'm about to ask hasn't been asked before; accurate and descriptive titles are extremely useful in determining whether a question that shows as a search result is relevant to what I'm looking for.
I didn't know about the question Scimonster linked to in his answer; that would have made my conclusion about question titles a lot easier.
