Good products tend to pay attention to the little details. Not all the details, but enough to make you notice. Lately I’ve noticed that the list of supporters or fans or whatever you want to call them on Facebook pages seems to always show a few people that are in your social circle, or friends of people in your circle if needed. 

This way, when you are browsing the page it says to you “It’s ok, look, your friends are here too!”.  They could have chosen a random set of people here, but I think it’s a nice touch.
