I dropped a couple just a few days ago. People I have either never interacted with or I just didn't make a connection with (despite trying). I chatted with several at both SteemFests and some were more friendly than others.
Not everyone who is a geek can have a personality I suppose, but most were OK. I now have 2 free slots to use at will.
Having met a few at Steemfest has had some influence on my votes. It's good to get to know the person behind the name. I have had some ask me why I dropped them, so they do monitor the votes.
