Google+ for marketers (interview with +Chris Lang)
I've been so busy getting ready for my trip that I missed this video in my stream when it first hit.
It's an interview with Chris Lang, who talks about how a handful of users (including Yours Truly) are using Google+ as their central platform and reaping the benefits.
He also makes an interesting point, which is that people who are doing this (the central platform thing) become easy to reach on Google+ with a mention, even though they're hard to reach otherwise.
It's certainly true in my case. I read every single mention on Google+ (adding a plus sign in front of the name), and reply or respond to most of them, but read only a fraction of my incoming emails, which are usually $#@!canned by my spam filters.
