Coming up with a decent title is sometimes like pulling teeth with my own stories, but I don't think I'm particularly affected by in with someone else's stories. If it's a pairing I like and/or written by someone whose writing I like, I'll still read it anyway. I'm far, far more likely to stop reading a story because the first few paragraphs don't hook me than I am because a boring title.

Sharing a title doesn't bother me either. thetreacletart and I both have a story called "Bottoms Up", which I didn't remember until I was compiling a Remus/Severus recs list recently, and we probably did it for the same reason: aiming for the same pun because our stories both featured drunkenness and anal sex. *g* I'm pretty sure I've seen another story that shares a title with one of mine, but off-hand, I can't remember what it was or who wrote it. In a fandom as big as this one, overlap of titles is bound to happen occasionally.
