The 2 biggest competitors in the firehose business are Gnip and Datasift. I am pretty curious if Gnip will pivot in a Twitter only firehose or it will continue to serve data from Twitter's competitors.
I wonder if Twitter will be able to use the data from Twitter's competitors transiting Gnip's firehose for their own analytics/machine learning/relevance purposes. (From a legal standpoint that is, I'm sure they have the technical chops to do so)
