You're doing a good thing! It is tough as more and more content enters the Steem ecosystem - impossible to keep up. Maybe thats a good thing though?
Imagine trying to keep up with reddit's traffic.. never could do it. That's a good goal for steemit too.
More and more content entering must be a good thing! :) But it also demands more people to give back to the community by voting, commenting etc. I see it as a two way street.
