Who owns the URLs you submit to Twitter? You? Or the Bird? I vote we should own our own URLs without having interference from the t.co Twitter link shortener unless we explicitly want it, and here’s why. We use Bit.ly to shorten all Boles Blogs Network links we send to Twitter and Facebook using our proprietary Boles.co URL. Yesterday, in the sidebar of our network blogs, the t.co link began to appear even though we were submitting the boles.co shortened URL to Twitter.
