i don't find that bothersome, it sells or it doesn't, the amount of watchers is irrelevant to me.
what does annoy me though is when you click on a listing and right over the picture there is pop up that says "15 people are watching this per hour" or whatever, why does ebay think i want to know this?
if they tell me there are alot of people watching i assume someone is more likely to have more money available for that item than me, also it tells me simply that i have more potential competition for that item. so if anything it puts me off.
