I actually do get quite a few profile views, and there are several reasons for it: viewers click on my name in a comment or when I answer a question; readers go to my profile when they read a hub they like and want to see what else I've written; people actually do a search after seeing my name on Google+, FaceBook or Twitter.
Because of this, I think it's important to keep your spotlighted hubs current and interesting. I change mine regularly to include a couple of my newest articles and seasonal articles. Sometimes I spotlight related articles such as a group of recipes or a group of articles on RVing. Another way to use the spotlight is to feature older articles that may be buried far down in your list.
I suggest checking your profile every few weeks to update it.
