It bothers me to be honest. Hypocrite here though, I used to use it sometimes, haha.

Neither. lol

Neither really annoy me tbh. If someone comments "neither" that just means they don't like either of the options presented, end of story. If they really disliked them they would probably (note how I say probably) go into more detail and explain their reasoning, but if it's something they don't care for there's no reason to go into detail. For example I don't care for dark chocolate or soda/pop, but if there was a poll for which one most people liked better (if I even answered it) I would say "neither". I don't hate the two or anything, I just don't give a crap about something so insignificant to me to explain.

As for "I guess" it simply means the user isn't really a fan of those options but they'd still prefer one over the other when faced with the choice. Like my reasoning above, people are too apathetic to give an explanation; they don't deem the options that worthy of their attention because of their lack of interest in both choices.

I hope that made sense. :/

I guess neither really bother me. I mean I don't really see the point on just saying neither and only that, maybe an explanation to go with it. 'Neither' is better than 'lol both suck'! I suppose part of it too is that I on occasions leave a neither. What I don't see the point in is not voting and saying something rude; it'd like just don't bother voting. That simple.

Neither..
