I just noticed a feature here that states that I have 305(!) fans on this site. Have absolutely no idea what that means since I’ve had almost no response to my comments and posts. But damn, I have 305 fans. Guessing I’m a fan of people that have no idea that I’m apparently a fan of them...
Amazing!
I think it's a neat feature, showing how many different people on the site have found your posts or comments engaging. (good or bad) It can make you feel appreciated for the contributions to the site. It takes all of us contributing, posting, commenting, even just reacting, to keep the site moving forward.
Next, you might get "followers" and those are people who enjoy your posts and don't want to miss any. Sounds creepy at first, but it's not. It's a compliment.
