Yes, that sentence got me as well. It's not that Twitter and Facebook aren't important (they aren't to me but that's irrelevant), it's that there are other arguably more important and very importantly (in this context), different, innovations from the US. When a person is saying "radical ideas...from...idea1, idea2, etc." one expects a continuum or line of DIFFERENT ideas. Not two ideas that are pretty similar and three in the same industry. The "From" scale is way too short for the article's concept. It's like saying "Radical clothing designs from jeans with no pockets to jeans with stonewashed fading and jeans which are dyed green". End nitpick.
