"psst, hey you"
You can make more money off of old posts.
Each month / quarter do a "round up" listing your favorite (top 3) posts (summarize why each one became / still is a favorite)
Each season do a round up list of older posts that are useful to the season.
I don't know if you do YouTube's but, if you do, round them up into lists, too :)
Thanks for all your tips!
