URL Shorteners are useful in space-constrained media like Twitter. But the dangers of such have been well-discussed (limited lifespan, hiding malicious links, usability, etc). But is there a nice way to pre-resolve shortened URLs from services like goo.gl or bit.ly? I'd like to do it at the time when the user enters them on my site/community.
LongURL has an API available for doing exactly this, and supports more than 300 different URL shorteners.
