No, I am not making it up: try to Google the web with this very phrase.
I don't particularly like Twitter. Maybe it is because of the people who clog it with incessant twitting. And while I appreciate that studies such as statistical analysis of 40 million Twitter messages may eventually shed some light on modern language evolution, I have no slightest inclination to follow any particular person.
So... ¿Tuitear o no tuitear? After some hesitation, I've created a Twitter account, @unaspalabritas, to put there some (mostly Spanish) words and expressions I come across, and their definitions. Vamos a ver si se trata de cualquier uso.
