That is an awesome Idea and some that Steem Inc should implement when someone goes to the witness voting page.
Most people are lazy including me and the only reason why I researched on the witnesses was to help out a friend who was researching what the top 20 witnesses did.
It would be great to have their latest witness update and the tech data would be very helpful.
I was looking at https://steemian.info/witnesses and checking the number of votes of some of the witnesses and surprised on how low some are even if the communities they have are so large/ Although we all know that vestments are the kingmakers though.
This must become a joint project of the witnesses.
