Yet again, this site updated it's shortener pages, just 2 days after I posted about them last time.
Shrinkearn is a popular url shortener, that is never struggling to monetise its links well, as the owner seems to be an expert with ad networks, however I don't really like the fact that they mainly monetise with fake buttons.
