It is a bit annoying, but most sites see it as more convenient, so we don't have to remember more usernames and passwords!
This is my first ever rant. I was just on a Houghington Post website via a yahoo link and I wanted to reply to someone on the comments section but in order to do so I had to have a Facebook account which I don't have. I don't have any social website accounts. And another minor irritation is with Yahoo's webmail accounts constantly asking for my SMS and I don't have a cell phone. It seems that the internet has become a place for those willing to be forced to comply to the wishes of owners of various websites rather than a place for people to receive and send information.
