Many people choose the witness at random, regardless of the status of the witness. it's good if we look back on who the witness we choose whether he is active or not. Sometimes the question arises whether I should choose the existing witness in the top 20 list? or is a beginner's witness worthy of my choosing ?. Here I want to re-let you know that everyone deserves to offer themselves as a witness because the more witness will be the better for the system.
But do not forget, that the task of a witness is to manage steem blockchain, so choose a witness who will do it. For those of you who still do not know how to choose a good witness, I will share 3 tools that I think you should try before you choose a witness or look back at the witness you have chosen.
1. https://steemian.info/witnesses
Is a tool created by @drakos, almost all the general information about a witness has been recorded on the tool. We can see the ranking of a witness, the number of voters, the missing block, the last block created by the witness, the age of the block, etc., we can even filter between active and inactive witnesses. For us new witnesses who have never created a block, then we are still classified in the category of inactive.
2. https://helloacm.com/tools/steemit/witness/
Is a tool created by @justyy The advantages of this tool is that we can check whether the witness that we vote still active or not. so we can take a decision to revoke votes to the witnesses who have been inactive. But I also wonder why up to this writing I made 
3. https://steemworld.org/@vesteem
Is a tool created by @steemchiller almost everyone knows and uses this tool, for me personally no day without seeing this tool to monitor my account's progress in steemit. a tool that is almost perfect, if we want to see the status and income of the witness we choose, we can immediately see it in the section Witness Details.
Hopefully this article useful to you, warm greetings from #aceh.
