hello Steemians!
I've been having trouble with my laptop and phone for a while now, battery issues, but things are finally coming together. The holidays are over, the Sun is shining bright and I'm getting back to full strength.
Even though I've been slow, that didn't stop me from curating the Nigeria community, or getting more interactive with the community.
Despite all the information available on the blockchain, many people do not seem to understand the concepts of what a witness is. . . . .
From the tables of 
Witnesses are generally voted for because they are trusted members of the community, positively contribute to Steem and Steemit in many ways, are qualified and experienced in administration of servers, and are experienced in cryptocurrency networks and software. Witnesses are expected to keep a block-producing Steem node running 24/7/365.25. They are also expected to provide an ongoing price feed of the value of STEEM tokens in U.S. dollars, set the minimum Steem Power deposit to create an account, set the APR% for the Steem Dollar interest rate, and in the future might set additional network variables. Witnesses are also strongly encouraged to run a seed-node to provide the blockchain to syncing clients.

Multiple posts by 
also give ideas on what witnesses do;
And some old posts by a nigerian 
also shows some interviews on witnesses and what they do as well
One thing I'm happy for is the fact that all transactions are available to see on the blockchain, whether it be in steemd.com or in steemdb.com. So if you wish to search for anything about witnesses, you can find them on the blockchain.
On who to vote for as a witness-personal opinion ahead
As im sure most of you have seen, voting for a witness should be a personal decision as witnesses can either break or make the steemit ecosystem. They are the ones that set the price feed for steem and maintain a steady system throughout.
Witnesses are the miners, well they break blocks, and process transactions on steemit.
As a rule , I vote on witnesses that are capable of handling the responsibilities of being a witness and not just here for the rewards.
I vote on witnesses that are working towards improving or making steemit a healthy ecosystem.
some of the witnesses I vote for
As can be seen below, the witnesses I vote for are all, in one way or another,connected and commited to building the steemit ecosystem.

Iv'e also had the liberty to see and knowsome witnesses that I think have the community at heart.

Some witnesses are dead
While speaking and having a good time with a friend of mine, he made me understand that some witness nodes have not been reporting back for some time, and indeed i went out and checked.
I suggest if youve voted or been on steemit for a while, you go back and check if the witnesses you vote on are still reporting back to the steemit systems.
I took a short stroll to a very useful site created by 
the reds are witnesses that have not reported for a while now, if its been over a few months, I would suggest you omve your votes to an active witness till the reds change
