Effective at spreading maybe. Maybe effective is the wrong word.The most effective ideas are the lightest, the ones which are able to spread without heavy machinery, or under the sheltering presence of higher values.
I'd love it to be true that the best ideas are the simplest ones or the easiest to transmit but I don't think that is the case. Some things are hard and counter-intuitive at first. There's a lot to be said for packaging though.
It's easy to deal with the pig headed and the ignorant but that doesn't mean you'll get much productive out of it.
