Am not using twitter much for what one departing Google exec calls "social" (as in "Social became state-owned, a corporate mandate called Google+" and his daughter's 2.0-savvy formulation "social is people* and the people are on Facebook").
Instead twitter is for important crap like tracking subway graffiti. The above is a recreation of a Florida tourism poster in the 49th Street N/Q/R station, which has been replaced twice in the last few weeks. Above is how I first saw it, with the handwritten message "Dolphin is not smiling - it's just a muscle crease, fool" and the thought balloon "Get me home!" It was completely replaced, and the next time I saw it the model's tooth was re-blacked and the thought balloon said "Set me free!" (I think). A fresh poster is up now with none of this graffiti -- looking forward to my next visit to the stop.
*I thought that was Soylent Green
