This is a very humble request : add a timestamp at the top or bottom of the pages.
Some examples why this is useful :
Governance Models | Couchers.org “In the coming weeks we will expand”
Profit and Incentives | Couchers.org “a few weeks ago”
Without any time reference, you have no idea if something still applies or not, etc. Add the date somewhere, and the reader can guess. Something like : Last edited YYYY/mm/dd could do.
