Example of fantastic customer service - BatchBlue

I'm a little skeptical about all this.<p>From:<p><a href="http://blog.batchblue.com/tag/tj-sondermann/" rel="nofollow">http://blog.batchblue.com/tag/tj-sondermann/</a><p>This smacks of astroturfing:<p>Slide 38: TJ Sondermann (@sondernagle) is the closest thing BatchBlue has to a mascot. Not only is he a great friend and full of great ideas, he actually came up with the concept of our wildly popular Twitter tee shirt (shown on Slide 39).<p>Account made 4 days ago first submission promotes FANTASTIC service at affiliated company.

A good example of how to do it right. Replies like that will convert interest into customers.

Where is the boundary between sales and customer service?

Has anyone here used BatchBlue? Any feedback on the service itself?
