Google+ seems to have been adopted by a lot of major players in the tech industry. Quite a few notable people post on it pretty regularly, possibly because it's hard to effectively tweet about technology issues in 140 characters.
I'd probably switch to it exclusively too if I could use it to export to Twitter and Facebook.

HN's own style guide has sound advice for how Linus might shorten his posts to under 140 characters.
I wonder if Google requested him and other major dignitaries to adopt their social network site. Is he on other social networking sites like Facebook?
If you follow the trending, a hugh number of trends are tech related and specific to Linux like #GIMP, #GDriveforlinux. A large number of G+ users seem to be geeks.
I'm really hoping he makes a Twitter account for his rant-I mean comments :D
