This is a proposal inspired by the overwhelming number of questions with uninformative titles on the site. Such titles tend to contain words like question, anyone, help, doubt, easy, exercise, homework, problem, stuck, etc. There are many of those...
Call for action
Consider improving the titles of the questions that you have answered. The best time to do this is right after you answer the question, since the answer bumps it anyway.
Awful titles get overlooked much too often. As an extreme example, I still remember a question titled "Proof or Theorem" (sic) which received three answers, all from 2K+ rep users, none of whom edited the title or commented upon it. (It's been edited since).
Having already put the work into writing an answer, adding a little extra to help your answer be found makes perfect sense. Also, coming up with a title for a question that you already read and thought about (even a while ago) should not be very hard.
Older questions
This query presents the list of titles that likely need improvement:
Questions with (likely) uninformative titles answered by a user
(UserId is the number in the URL of your profile page.) The query also shows current tags. When editing a title, it's best not to forget the tags and formatting of the question, either...
As noted above, the ideal time to fix the issues with title, tags, and formatting of a question is right after answering it, when there is no extra bump involved. But better late than never. Usual caveat applies: don't flood the front page with rapid-fire edits. Also, consider the quality of the post itself. If it's at or below the current average of the front page, then the editing effort is better placed elsewhere.
