"We launch new features in Gmail almost every week, and people learn about these features from different sources -- friends and family, the news, this blog, or our what’s new page. But heavy Twitter users like me often have to rely on @google and other users for updates related to Gmail. Starting today, you can now get all your Gmail news, tips and tricks directly from @gmail."
