If the poet is known to me and one whose work I like, I'll read no matter what. Since I've been posting in a small forum (CA), I read all of the poems there.
If I foray into open, it's usually by the title, which is supposed to be from the heart of the poem, though it can often be ambiguous, clouded, or misleading.
I feel titles do not have to reveal the poem's meaning, but sometimes, if a work is abstract, it can help the reader to identify with concepts. Titles which immediately put a question into my mind as to what the poem may or may not contain usually grab my attention first. Obvious titles would only get notice if they were of a subject matter I was interested in, and, of course, everyone has their own tastes.
As to how to make titles more interesting...I think one should try to form a title that speaks of the poem, yet makes the reader curious as to what it contains. I know...easier said than done. Well, I tried.
