Last week, Twitter tweeted, “If you’re currently using Old Twitter, we want to let you know that you’ll be upgraded to New Twitter this week.”

Well, here it is Monday, and the roll-out has been completed. Twitter announced as much via a tweet today.

“Old Twitter” refers to the old user interface. The new one was introduced nearly a year ago, and has been available as an option since. Many people have been using “New Twitter'” since then without looking back. Frankly, until last week, I had almost forgotten that “Old Twitter” was still an option, but it was. Just not anymore.

It was good of Twitter to ease users into the new design by keeping around the option to use the old one for this long. Major redesigns are often greeted with a great deal of hostility. It’s much easier to reduce hostility when you aren’t forcing the new way on people.

Of course now, that way is being forced upon people, but at this point it’s not such a drastic change, because people have had a year to get used to it. Last month, they went ahead and switched the search feature into the new interface, perhaps preparing users a little bit more.

Still, opinions are mixed.

Personally, I think New Twitter is a drastic improvement over old Twitter. It simply makes it easier to put conversations into context and see various media. The following video shows it off:

Do you like the New Twitter better than the Old Twitter? Let us know.
