Does anyone know what makes a category appear in the main tags on the front page? I see many categories that have only a few posts and you can see them on the front page, and there are some like #music that one would expect to see and they are actually not there.
What are the criteria to make a category appear? Is it run by a code or Steemit inc. decide what we see on the main page?
The Russian clone of Steemit, Golos is giving you an option to save your favorite tags as bookmarks.

The moral of the story: During the space race between Russia and USA in the 50's NASA spent enormous amounts of money to create a pen that can write in zero gravity. The Russians used a pencil.
