Frequency Limited Posting
Might it be reasonable to make the assumption that it is very difficult to post valuable and original content with a high degree of frequency? If it is reasonable, then we could define a new category (Frequency Limited Posts) that only displays posts from accounts that have committed to posting a maximum number over a certain period of time.
If it was a successful category for generally improving the number and visibility for quality posts, it may then be reasonable to have a full set of existing categories (trending, hot, new, active etc) for posts coming from frequency limited accounts.
The incentive model could be adjusted to make posting less frequent, higher quality content more attractive.
If implemented, this would have no impact upon the other steemit channel where posting can occur at far higher frequencies. Accounts that opt for frequency limitation would not have their commenting or voting limited.
What about daily bloggers with large followings? Their posts will generally be followed and rewarded by followers who already know how to find their content.
