You have a point about grammar. 

I use Medium extensively. The first thing I realized on Steemit was that the grammar on Steemit is considerably worse than Medium.

That's a shame, because Medium doesn't pay anything to their regular users and Steemit does. I agree with you that we need to be careful about our grammar.

Moreover, I find it a pity that Steemit stops rewarding posts after the first seven days. Some content is evergreen and keeps attracting new views. Why not reward them after the first seven days?
