Here are my list of witnesses that you might consider following:

• @c0ff33a because i am able to reach him in discord and in the platform. He is very active that he cares a lot for the small fishes. He may be a busy man, but he aint busy joining in the comments in most of engagements and posts. And lastly, he widely supports a lot of communities here especially the @welcomewagon

• @steemgigs because #ULOG was the first tag I used and still using up to now, they support users by upvoting & resteeming their post. now their community have gotten bigger & bigger.

• @good-karma because he developed the first app i mostly used, the esteem app. He constantly supports its user and provide apps both in mobile and desktop for better usage.

• @yabapmatt because im a steemmonster addict! 😁

This is just my opinion, i’m basing it with my experience with these people. Hehe ✌🏻
