I went to YouTube normally this morning, and saw this:
Looks like Google is getting Facebook Connect soon. You can now sign up for YouTube using your Facebook account. It's surprising to see that Google is doing this. They have their own integration with online services, and many people regularly use their Google Account to sign into various services. If you check out DISQUS, which I use for comments on this blog, you'll see that you can sign in with your Google Account as well as Facebook.
Facebook Connect is so popular with so many sites now. You can integrate your social self with almost any online service. Now even YouTube. Brian Glick says on the YouTube Blog that you can now choose to share the video you are uploading immediately with your friends on Facebook and Twitter, and also with people following you on Google Reader.
