If you have to end your thread title with an elypsis in order to draw up some intrigue so people click on it, you should take that as an indicator that the thread is not worth starting.
Ellipsis (plural ellipses; from the Ancient Greek: ἔλλειψις, élleipsis, "omission" or "falling short") is a series of dots that usually indicate an intentional omission of a word, sentence or whole section from the original text being quoted, and though necessary for syntactical construction, is not necessary for comprehension. Ellipses can also be used to indicate an unfinished thought or, at the end of a sentence, a trailing off into silence (aposiopesis), example: "But I thought he was . . .". When placed at the beginning or end of a sentence, the ellipsis can also inspire a feeling of melancholy or longing. The ellipsis calls for a slight pause in speech or any form of text, and can be used to suggest a tense or awkward momentary silence.
