On Tuesday Google launched Google+, a social network to compete with the likes of Facebook. Some people like it. Some people don't. But one would assume the search giant's top executives are the most enthusiastic of Google+ users. Well so far, as Techmeme's Lidija Davis points out, they're still just warming up to the social network.

Out of the gates, Google CEO Larry Page shared some warm words with his colleagues: "Best of luck to the team, and congratulations on such a great effort so far!" That's it, though, which is sort of underwhelming engagement for an executive who told his employees earlier this summer that "When we release products, try them and encourage your family and friends to do the same" while tying their pay to Google's performance in the social space. Here's what his meager page looks like now:

Meanwhile, Google's other co-founder, Sergey Brin, is utterly speechless:

Over at YouTube, founder Steven Chen's not so much of a talker either but at least he's changed his photo (also props to Chen for having at least 18 friends in his circle, unlike Brin and Page who don't appear to have any, though perhaps that's a privacy feature):

And then there's Alan Eustace, senior vice president of engineering and research, who at least has his page up.

Of course, everybody deserves some time to get used to a new social network, so we presume there will be an uptick in usage in the coming weeks. Still, you'd think some of the company's top brass would at least have profiles by now. Some notable absentees include: Eric Schmidt, executive chairman, Patrick Pichette, chief financial officer; Nikesh Arora, president of global sales and business development; Jonathan Rosenberg, senior vice president of product management; and Marissa Mayer, vice president of location and local services.
