DataSift now grabbing Tumblr data, as well

DataSift, one of the two companies (along with Gnip) granted real-time access to the Twitter firehose, now offers real-time and historical analysis of Tumblr data. While it’s best-known for Twitter, DataSift actually analyzes dozens of social media and commenting platforms, which is pretty handy if you want to compare sentiment, engagement or whatever else across platforms where people behave quite differently.
