I'm not bothered by the brightly colored bikes lining our sidewalks. And when I see one that has fallen down? I pick it up.

For a bike share program to succeed, they need to be everywhere. Just like taxis are everywhere in New York City. Who would ever take a taxi somewhere if they couldn't count on a taxi being there when they wanted to return?
Besides, today bikes are not everywhere. Cars are everywhere. When you see bike parking on every street and in front of every store, required by city code, and paid for by the taxpayers and/or storeowners, then you'll know bikes are everywhere.
Bikes fall over. The world has been in need of a Thomas Edison to improve bicycle kickstands since forever, but it is what it is. In the meantime, the rule for bicycles should be the same as the rule for open doors. If you see someone has accidentally left a door open, close it. And if you see a fallen bicycle, pick it up. It's waiting there for you. Be thankful someone left it.
