Today I changed the title of the question "Interesting Mathematical Induction Series Proof" to the more informative "Induction proof of lower bound for $\sum \sqrt n$". It occurred to me that most titles that contain "interesting" are similarly vague. A search confirmed this. Not every title with "interesting" was completely useless, but most were.
There are 113 of these. I thought that giving them better titles might cause them to appear more often in relevant searches, or make it easier to select them as relevant or irrelevant when they do appear in searches. On the other hand, perhaps they are likely to be poor-quality questions, so perhaps it is a good thing that they have such a clear indicator of low quality in their titles. And perhaps it's not a good idea to bump 113 questions that are likely to be poor-quality.
I don't know. Is there value in trying to change the titles of these "interesting" posts?
