Do you have any shots in your online portfolio, that have been up for weeks but no one looks at... still you can't bear to take them down?

Nope. I always replace the shot with the least views. No hesitation. If I like a shot that much, I can print it, frame it and hang it in my livingroom. No point in promoting myself in public with something no one in the public likes.

I often look but do not touch.

You can't always go by the # of hits as the reason an images stays or is replaced.  The higher # of hits will usually go to the ones showing the most skin.  Those that are more serious about viewing your work are going to check out photos in other categories as well.

That's true. However, it's not a bad indicator to start with. Especially, if one is squeamish about soliciting general assistance from the MM community in deciding which images go and which ones stay.

Lol. I actually did that one day on MM and boy was it helpful. So nice once in a while not to rack the brain on something that would seem trivial. But, like Star eluded to, can be difficult decisions to make for sentimental reasons and what not.
