Whenever I publish a blog post, the Google+ dialog box pops up. It's really irritating.
And you know what's really, really irritating about it? I end up chasing the damn "Share" button all over the screen. Of course I want to share the blog post - stop asking me, already!
Sodding thing. "Usability" is not one of their strong points. (Perhaps that's why they don't have a hope in hell of catching up to Facebook?)
