Tweet Button : Short but Readable URLs
While posting through TweetButton, Twitter translates your URL to a short URL, say in this example, http://active-player.inspions.com to http://t.co/0toCfbl. This is all but normal.
But a nice improvement Twitter did was instead of just posting the short URL in the tweet, it posts a readable URL while still linking to the short URL.
It totally cool improvement and makes tweets more readable.
Compare it with this following tweet of this very post, but using Google’s short URL.
