none come to mind that moved from offline to online, but MANY where online augmented existing offline communities. Take User Groups as a classic example of this in the tech industry. Scrapbooking is another classic example in this space that was really offline and now very prevelant online. I don't think the answer is replacing offline with online, it is what can online do to enhance offline and vice verse.
