After countless leaks and rumors, Twitter has announced a subscription plan. This one is called Twitter Blue; for $2.99 a month, users can unlock additional functionality, including the ability to undo a just-sent tweet (not the edit button). You will also get access to a brand new theming as well as bookmarking features.

Twitter Blue is launching today in Canada for $3.49/month CAD and Australia for $4.49/month AUD. The users in the United States will have to wait a bit more as the feature will arrive later this year.
