.Co gets more recognition thanks to Twitter.
Today Twitter launched its Tweet Button, which allows people to tweet links from web sites that have integrated the button:
Twitter is great for sharing interesting things you find on the web. In fact, close to a quarter of all Tweets include a link in them. Despite the high volume of sharing, there is plenty of room to make it easier. Copying and pasting, link shortening, and bouncing between browser tabs just to share a link in a Tweet is too much work.
Today we’re launching the Tweet Button to make sharing simple. It lets you share links directly from the page you’re on. When you click on the Tweet Button, a Tweet box will appear — pre-populated with a shortened link that points to the item that you’re sharing.
That shortened link Twitter refers to is a t.Co link, which means more and more people will become familiar with the .co extension.
