Make bike sharing viable

I asked this question in the Wisdom of the Crowd:

How can we make bike sharing viable?

Here are the responses: (57 Votes)

33 % - Let all the operations close down; we do not need bike sharing.
30 % - Make it a part of the public transport infrastructure and charge a modest fee of $0.20 per ride.
19 % - Leave it to the market to sort it out.
18 % - Allow the free use of the shared bikes but impose rules about their parking.
