Easy to implement. To collect and put into an intranet blog important informations about company culture, interesting articles about working environment etc. It is always easier to refer to well known informations than to explain every time the same. Now the hack. As you have enough informations you put the publishing in the loop (it means publish the oldest one as the newest one).
It works without you! But be careful it is better make review of the articles and adjust them to the current situation or drop them.
