Google replaces Reader ads in empty Gmail inbox with Google+

If you ever happen to have no messages in your Gmail inbox, you might notice Google’s subtle way of promoting Google Reader with the small ad for Google Reader (below). Now, Google has removed the “Try Google Reader” link and replaced it with a new message promoting Google+ (via Google Operating System blog). The message now reads, “No new mail! See what people are talking about on Google+” (pictured above). Within the new message is a link to the “What’s Hot” stream of Google+.

With the launch Google+, and its incredible growth (about 750,000 new users a day), many warned the growth was attributable to Google’s ability to pull in Google+ users. So, what happens when it runs out of Gmail users to bring in? Google may have already thought that through with a recent update to the Google account creation process requiring users to both create a Gmail account and automatically create a profile and Google+ account. In other words, not only is the company pulling in Gmail users, but also anyone that wants or needs a Google account for other services.
