I have used STEEMBOTTRACKER for a while, it has helped my posts to be more visible and trending, while I have lost time and money (not always) on bidding! So far, I'm happy with the engagement SBT brought to me, having more real comments from readers, interactions, more REAL followers etc.
So I show my appreciation for the service and the founder, 
But I have some questions and points:
- There is lack of information for people regarding the bid bots and other bots. instructions how to use them etc, especially post HF20. I tried to do a bit in few posts after the HF20, like this one
- Why the site performs "Security Certificate Error" with MS Edge and FireFox?
- We need to study the impacts of Bid/voting Bots economically on the ecosystem.
about the 3rd issue:
I have always been skeptic and doubtful about systems with "money out of thin air" and STEEM's reward pool maintains same. I know even US Dollar is a money from the thin air! but then it comes to trust in US economy, the market cap of US economy etc.
Same studies should be done on STEEM blockchain to make sure it will run sustainable. SteemBotTrakcer can be a source of data for such analysis in my perception.
There are too many data on technical analysis and chart analysis, but I never read something about how the crypto market can stay sustainable in a long run.
There are obvious facts: if more people adopt the idea, it will become more stable. yes, but we need to be able to convince them. in my opinion, such studies and data will give us the right arsenal of weapons to convince people.
I appreciate your comments and advise, and I will be thankful for what I learn from you.
