&#62; That team were forced to sign NDA's, and taken to a very quiet, secluded meeting room where some cool new Facebook-backed open source project was described.<p>This caught my eye - an interesting use of the term "open source" that I haven't previously been aware of. This is only a single datapoint (and the article states the project is going to be opened up anyways), but I do have a feeling the term has been diluted and joined the buzzword ranks.
