The trouble with only passing on verified ideas is that it stops you being able to pass on ideas you wish to get verified that need significant resources to do so, and need the help of others. E.g. higgs boson, an AI theory, a new low level computer design.

So perhaps a way of coding ideas, e.g in need of testing, tested myself, tested second hand, publicly available test data.

Colour coding comments on a forum might be a good place to test this kind of scheme. Then people can easily discriminate what is verified and what is speculative.
