Good, understandable and sensitizing explanation of what we can do with our upvote. I think the main sentence is:
"Vote on people and articles you like, the system is setup so that good authors get rewarded and poor authors also get what they deserve."
Sometimes we may not achieve the best back by our upvotes, but we will sustain a good author!
I also personally think bot are ok but should be used with consciousness. They have negative and positive points, and a lot depends, as in many cases, how users do use them....
There are also bots that serve certain purposes, like @isotonic. I always make a point of using that one.
Right, there are bots that are for a cause like that one!
