I think for non-elites it's about the same. It depends on how you conceive "ideas" of course - whether you restrict the term purely to abstractions, or broaden it to include all sorts of algorithms, including the practical.

Non-elites aren't concerned with abstractions as much as elites, they're much more concerned with practical day-to-day matters like raising a family, work, friends, entertainment, etc.

Take for instance DIY videos on Youtube - there are tons of them nowadays, and that's an example of the kind of thing that non-elites (and indeed elites to the extent that they might actually care about DIY) are going to benefit from tremendously. And I think it's going to be natural for a non-elite individual to check out a few (after all it's pretty costless, except in terms of a tiny bit of time) and sift out what seem like the best methods.
