OK, so the Facebook API is probably (one of) the most used API nowadays, maybe even before Google APIs. Assuming out of N developers each has the same chance of "dislike" for some API, it seems to me this pie-chart just nicely shows -roughly- how developers are distributed across APIs. In other words, I don't see how the general distribution of API use [edit]by the surveyed developers[/edit] [del]in the survey[/del] was accounted for.
