I follow a few folks - I notice I take a second look if Karyann updates her wishlist because she and I have similar tastes Following Foxhack is fun for lols
That's pretty much my reason for following most of the people I follow
Usually, it's because when they add something to their collection or wishlist, chances are that it's something I might be interested in!
I also stalk IRL friends just to know when they buy something for their collection. None of them post on the forum though, boo.
