I used SBI for over a year at Steemit; I had delegated a big chunk; here are my thoughts:

• It provides a good return for when you do post
• It provides a good return for other creators when you don't post
• Completely agree with @jongolson; people need to be rewarded to create, or they leave.
• Completely disagree with the "circle jerk" theory; it is technically correct,and functionally wrong. SBI is an investment in the platform. It is not "free money", because there is a price to buy into mutual support.
• Abusers are kicked out of the program. (Digression - I know a lot of ppl complain about quality of posting, but that is subjective; I think that catpic posting and isn't blockchain so cooooooooool posting are complete crap. It's my opinion. But those posts aren't spam. If we get butthurt b/c someone wrote and got rewarded for a post that we ourselves don't like, then we don't have the foggiest clue about what this platform is intended to do - ergo, save the post-hate for spam and plagiarism)

I will be re-delegating to SBI once I go over 10000 HP. Should be within a couple of weeks of powering down SP from justinccp-it
