We all like to pick on Google Buzz, but c’mon reshare? The obvious criticism to make is that the re- prefix is superfluous because share functions just as well in this context. Once we make this criticism, however, it’s not much of jump to see that retweet and reblog are similarly redundant. But this doesn’t feel right, does it? A “blog” or “tweet” button would seem weird, right? This might seem handwavy, but what this intuition tells me is that the prefix re-, at least in this context, is shifting in meaning from simply repeat or redo to reproduce.
