What you're saying is that the process of experiencing the maxim and internalizing its lesson is more valuable than the maxim itself. I disagree - the bible and quran's lessons for life have been shared with and digested by many millions of receptive minds. It is the sharing of knowledge and experience, accumulated over generations, that allows our species to make the incremental improvements that leads to advancement. Keeping truths to oneself may be valuable, but if you have a powerful truth, the leverage you obtain by sharing with the world is a lot more powerful.

Nevertheless, you do have a point - how do you create value for people through a maxim that they haven't experienced? I would argue that the credibility of whom the maxim originates from is very important.

For example, The Bible has tremendous credibility and respect from its believers (and many non-believers too); this significant ethos prepares people to be receptive towards the maxim. Or for a modern day example, imagine the difference between a regular joe giving you career advice on his blog (as you wonder, 'who is this guy?', vs. reading maxims from Mark Cuban's blog.

In order to solve this problem of ethos, a site would have to employ reputation or karma for each maxim, with people weighing in on how valuable / truthful each maxim has been through their personal experiences. A maxim written by an anonymous becomes more credible when Mark Cuban, PG, or other famous people publicly vouch for it.
