There's alot to be said about a witness engaging in posts. If a witness actively engages with my posts I will vote them for them as witness. Kind of like the way I vote for the local politician if he gets rid of the pothole near my house or he puts a rush on a passport for the child. I will vote for them. I use the same logic with Hive. The local politician may be shite and bad at national level but I will always be loyal if there is engagement there.
