As it stands steemd has a 500 post limit to fetch, this could also be extreme for a server to handle, the steemjs currently fetches a limit of 100 (this would be on the client side), and also there is a difference between tags and categories.
Category -> First Tag that you reference
Tags -> All tags given to a post.
Of these what would be the ones people would like to see ? All tags or the one the author chose as main tag (category)
