I suspect most people will be able to use Facebook + Skype before they receive invitations to Google’s pre-beta Google+
The product has been built on Skype and will include a desktop component. It’s not clear to me whether that means it will just work if a user has Skype already installed on the computer, or if additional software will need to be downloaded even if the user already uses Skype. But it’s clear that there’s very deep integration between the products, and from the user’s perspective, the product will be an in browser experience.
And this also brings Facebook even closer to Microsoft, which is a Facebook shareholder and has a pending acquisition of Skype. The guys in Redmond must be smiling today, something that happens far too infrequently at Microsoft HQ.
