I have been using steemfollowers for some weeks now and I can say it has helped me a lot. It deals with the biggest problem in steemit, visibility. Instead of using voting bots now my posts can have more organic views and I can promote them even more. 

As for suggestions, number 2 could be nice, see more features if you are premium like less cost for promotion or maybe more % points. However, I can see how whales can rack up more points this way but could be worth it.

For number 3 I can see the problem. Maybe you could make it as a bonus, if you vote one daily steemfollowers posts you get 2x points for that post compared to regular votes. This way you earn more points for your vote power and you have the option to do it or not. With a 2x bonus I would definitely do it.

I am not sure why the market was taken down but if it comes back you can take a percentage (10% or something similar).

@jerrybanfield do a lot of steem budget proposals. You could contact him and maybe send a proposal for him to review.

I will see if I have more ideas. I think these projects specially steemfollowers are one of the best features steemit could have.
