Yes, I do need to examine more of the witnesses and their stats to figure out who to vote for - I just thought maybe there were some you voted for due to their intentions on a personal level - these are how I ideally choose who to vote for, coupled with their technical abilities and performance, since they will maybe influence which hardforks get support and which don't.
Thanks for the link to steemdb, I hadn't seen the witness block log there before - I was surprised to see that your graph only shows a few blocks from the last few days. I was able to see the list of witnesses that you are voting for in there too (although it might be a bit out of date since mine is out of date - i stopped voting for jerry and added a couple of others). I happened to notice that these ones in your vote list are running old versions of the witness node software:
joseph
theprophet0
krnel
It would be greaat if you would consider switching one out for me to give me a chance to perform better. :)
