While I agree minnows should largely upvote their own comments/posts, I wanted to make everyone aware it doesn't really do much. It takes 112 to 119 days of upvoting your own comments 10 times a day just to double what you have(assuming no one else upvotes you). Upvoting yourself when you have the 75ish steempower they give you doesn't really do anything because it goes away after a certain point. You might get 30 days I think it is before it goes away, or until you earn a certain amount.
The only real way to get ahead here is making quality posts frequently, or commenting good comments a lot, or having a following to bring with you, or buying into the system(I did purchase about 195ish Steem).
Upvoting yourself without first buying more Steem is an exercise in futility, because you will be making less than 20 cents per day when you do your 10 upvotes. A person could make way more by putting some thoughtfulness into their comment or by making their ow blog post.
Usually when someone upvotes a blog post I make, I upvote them back then and there or a day or so later. I go back and look at who upvoted me and click their name and upvote if they had a good blog post. I think that is how Steem should be used for the most part. But just my opinion from a newbie! :)
Although I had noticed this trend of upvoting of own posts and did not think much of it, I just happened to see this conversation. @truthforce, I am in agreement with the points you have raised above.
