Solid picks & certainly 4 witnesses that are doing far more for the community than themselves. One trait I happen to admire about witnesses that I choose to cast votes for. @guiltyparties is certainly one pillar of the community and active at that. I often read the activity in the Military Vets of Steemit Discord and this dude always around, which speaks to the level of commitment.
On that note, @jackmiller is another that I feel confident mentioning when speaking of commitment. I've had the pleasure of chatting with Jack on many occasions and also working on projects together since late last year. Jack is tanciously driven and his level of commitment is intense - no bull. A real stand-up guy who puts himself out there and there's no question he stands by his word - actions say it all.
@surpassinggoogle is another pillar of the Steemit community that earned my respect and admiration early on by showing immense support to those of us just starting to test the Steemit waters. Watching @steemgigs really come alive this year and see the website launch was exciting times and would not be possible without the dedication put forth to create such a kickass website for freelancers. Having said that, I won't disregard the efforts of @enginewitty and the useful info that new users can rely on as they are welcomed into this wild ecosystem. It's awesome to see the real human effort that makes the Steemit experience enjoyable for many users still trying to figure out how to use this platform. It makes all the difference to have genuine hoooooomans available to help and offer guidance.
No robot can do what these people do
Will make sure I've voted each one of these witnesses and I suggest that anyone who wishes to enhance the Steemit platform simply observe the actions of these 4 candidates.
