I took a look at the witnesses page located at https://blurtwallet.com/~witnesses today. I think there's a one major it can be improved to help users pick the best witnesses for them.
Display Witness Fee's
Witnesses can vote on a few different fees, Account Creation Fee - Fee to create a new account, Operation Flat Fee - Base cost per operation, Bandwidth Fee/KBytes- Surcharge on operations determined by size in bytes.
Since this directly affects users, they should be able to see the decisions made by witnesses when picking who to vote.
Upvoted! Just because you do not have outgoing delegations / report plagiarism.
