Lots of Google applications still had a “Beta” tag on them (including Gmail) for several years. It makes one wonder why on earth an application is still in beta for years but lots of people can’t seem to live without it. When Gmail went down, it’s like the whole world shook in terror. I guess the tag “Beta” wasn’t helping at all.
Well, today Google decided to remove the Beta tag out of their applications such as Gmail, Google Calendar, Google Docs, and Google Talk. If for a silly reason you still want the tag Beta on your Gmail logo, feel free to enable the “feature” on Gmail’s Lab Settings O_o
