You may have heard about Google+, the hot new sharing product from Google that went official today, and it sounds cool (sounds cool, but remember how cool Wave and Buzz sounded? Let's just say we're reserving excitement so far). But one exciting thing about the new project is how cool and smooth it looks, and TechCrunch has noted the reason for that look, based on Steven Levy's reporting: it's designed in part by Andy Hertzfeld, one of the members of the original Macintosh team back in the 1980s.
Hertzfeld now works for Google, and supposedly he was let free to exercise his creative influence as he liked on the new Google+ system, creating something for the folks in Mountain View that looks like it might have come from the early days of the Cupertino company.
Hertzfeld even credits some of his influence at Google to Apple's own resurgence lately, saying that Apple's sky-high relevance in the tech and mobile industry may have "had a little bit to do" with his chance to help create Google+.
In other words, when you finally get one of those invites that are starting to float around, and finally log in to the system to see what it is and what it's like, take note of any Macintosh-related influences you might see. Odds are, they're Mr. Hertzfeld's work.
