For Hounds who USE "People I'm Reading"-- 4 of 5w's & 1H please?
Kris, I used to do it because I really would regularly go to that list and click on certain people to see what they were up to food-wise. I rarely use it anymore. Actually there are two CHs with whom I'm friendly offsite. They I will regularly/daily check up on. I knew a CH who would regularly count to see how many people were "reading" her. I thought that was more than a little odd :)
I add to my "People I'm Reading" list those who amuse or enlighten me. I use the list by clicking "My Reading List." This alerts me to threads I would usually pass over, such as the thread "Celiacs, Sacraments, and High Holy Days?" http://chowhound.chow.com/topics/982461 I would have skipped it, but, knowing someone I like reading has participated I clicked on it. So glad I did because I started my day with a good chuckle.
How? Click on someone's icon or name, view their profile and "+Follow."
I will add that I am fairly ruthless when it comes to un-Following someone. If I find my reading list clogged with things that don't interest me I will find the common denominator and "-Follow." While I thoroughly enjoy reading many things, a posty-pants can ruin my reading list by posting on every thread on one board.
