Your increased awareness is probably getting you to now notice cyclists who've always been there, but I think overall there is an increase in bike commuting. Here in West Texas, bicycles seem to be thought of as children's toys or the last resort of the near homeless for transportation over the 30 years I've been commuting off and on. But lately, I'm not only seeing more commuters, but they are also more seriously outfitted: branded bikes, helmets, panniers, etc. It's been encouraging to see.
