Most professionals are already very familiar with Skype and other one-to-one video services. Before the announcement, Facebook CEO Mark Zuckerberg said he would be unveiling "something awesome." But Skype integration is not awesome. It represents a minor convenience compared with clicking on a browser tab and initiating the call from skype.com.
You know what's awesome? Google+'s Hangouts feature.
Just select that "Staff" Social Circle and launch a Hangouts session, and you're suddenly doing a very smooth and reliable video staff meeting. You can show the group a video for everyone to watch at the same time, or just talk and have your meeting.
(Yes, Skype has group video, but it appears to be less reliable and actually costs a monthly fee. Google+ Hangouts is solid and free.)
Google+ Hangouts is better for business than Facebook's new Skype integration.
(I would have listed a fourth "killer feature" that Facebook would need to copy to survive -- group chat -- but Facebook has already copied it as part of their announcement.)
Now comes the interesting part. I believe Facebook will soon copy the second and third of these features, but not the first. The entire Facebook service is built around the concept of friending -- they'll never abandon it. And this will enable Google+ to grow.
No, I don't think Google+ will "kill" Facebook. But I do think Google+ will succeed.
Meanwhile, you need to know that Google+ is better for business today, and will probably be better for business tomorrow. So I'll see you on Google+!
