In my previous post, I presented some of the problems that Twitter is facing. However, Twitter is moving ahead, now it will soon be using t.co as its URL shortner. Thus a long link such as http://www.amazon.com/Delevering-Happiness-Profits-Passion-Purpose/dp/0446563048 will be wrapped to http://t.co/DRo0trj .
All the t.co based links will be of fixed 20 characters. However, the best part is the link t.co will let you know where the links are going. This is possible because Twitter is including metadata with each tweet.
Another positive effect that it will add to Twitter is that it will reduce the spam. It does it as it observes the distribution of each link and warns the uses if it considers the link malicious.
The introduction of t.co might cause problems for bit.ly. It will be intersting to see how bit.ly will compete with t.co.
