What I find most interesting were Maples comments on only about 10 'good' companies a year. If I think about the early majority and late majority segments, this makes a lot of sense to me. Friends in those segments are just barely starting to use and understand Instagram, let alone, transportation start-up X. I wonder if we're at a point where good ideas don't work simply because the market is up against the we-can-only-learn-so-many-new-things-per-year wall. Of course that would be born out by a lack of series A's for those companies. Right idea, wrong time. Makes you kinda want people to open source their failures, so that in the future, you already have a place to start from on an 'old' idea.
