Steem improvement suggest

This article uses Google Translate. I'm sorry if English is bad.

• Can not accept many articles -

If you have written 100 articles instantly around the world, subscribers can see only about 10 of them.
This is because only about 10 articles are displayed on the monitor screen. Because of the fact that they wrote a bit ealier, the articles below are hard to find and read, no matter how good they are.

I think steemit should increase the number of articles displayed on the screen.

• The need for categories -

steemit need to create categories that are appropriate for the type of articles.
It is now a tag, but it is uncompotable compared to a professional large community site and it is hard to find many people in the field you want.
I want you to quickly and easily display the kind of articles you want on steemit.

• Is this mining by writing? or is this community a virtual currency that coexists? -

Steem powered people get big rewards and lots of votes in a few lines. But those who are not will not be able to do so and get deprived.
Is this a simple mine to write? or is it a new concept with a mix of community and virtual money? Before I came here i expected the latter. But the current steemit seems to be the previous example.

I hope steem will be a good site with many improvements.
