I was part of the team that created Crunchbase at Techcrunch and it is really sad to see what has happen, since the way People+ are using Crunchbase is exactly as intended with the design.<p>I can remember the specific conversation about picking CC-BY+A, it was because we wanted other apps to use the data, even if they were competing with us (and they were)<p>It also seems they have dumped the open API, previously you could just add '.js' to any page and get a JSON representation of it, no developer signup, no stupid API key, etc.<p><a href="http://api.crunchbase.com/v/1/company/facebook.js" rel="nofollow">http://api.crunchbase.com/v/1/company/facebook.js</a><p>My impression now is that since the AOL acquisition Crunchbase has tried to retract a lot of its openness, which was a big reason for its success.<p>I think the key difference is that we saw Crunchbase as a free service to the startup community that would reinforce Techcrunch, while AOL see it as having a distinct and independent commercial value.
