Will the real social media expert please stand up?

As a newly launched Social Media consultancy agency we cannot agree more with this post from social media consultant, trainer and speaker, Mack Collier.
It’s not the quantity of clients you have but the quality of the work you produce for them that should be the real trigger…

Let’s say your company wants to hire a social media consultant to launch a blog for you. You’re down to two candidates, one has a list of 12 different clients that they say they have helped developed blogging and social media initiatives for. The second consultant doesn’t list any clients, and appears to be brand new to consulting.
So you naturally want to go with the first consultant, right?
But what if you check the consultant with the multiple clients, and notice that their blog has almost no comments, and the newest post was 27 days ago. And their SiteMeter link says their blog averages 29 visitors a day.
Then you check out the consultant with no clients, and see that their blog has an avg of 4 new posts a week, every posts gets at least 5 comments, and their blog averages 500 visitors a day.
Now who do you hire to create a vibrant blog for your company?
