For some time now I have not audited my list of witness votes.
This is a task that I consider very important within the few that every good steemian should do from time to time.
Each steem account can vote for up to 30 witnesses, so, as you can understand, in a certain manner, it is our duty as well as our right as steemians to vote for witnesses which have contrasted solvency working as so, if we want to ensure the good stability and performance of the STEEM Blockchain.

I think it was before HF21/22.
In fact, I miss a tool that helped me a lot in the past.
This tool, called DUPLIBOT and created by 
The criteria I chose on which witnesses to vote was based not only on the fact of keeping the blockchain stable by signing blocks regularly and updating their feed price as well as the blockchain code whenever necessary but also, assessing the activity of those witnesses, so, for instance, if they used their Steem Power correctly, upvoting regularly, if they regularly wrote a post and participated in comments within the community.
In order to check these points, DUPLIBOT was extremely useful. I could extract exactly the information I wanted as for instance the following:
Now, this utility has stopped working so the management of the witness list audit has become a very difficult and manual task.
If I used to audit my witnesses once a week, today is impossible.
Tools as the following can help in determine the efficiency of the witness nodes but I miss information that is relevant for me as if they post or upvote regularly:

Just, keep using your witness votes doing an important work.
My current Witness list is:
