A good tagline is like much most marketing. Lots of experiments with split testing of multiple taglines to see which one the market responds to the most.
As for the comments regarding branding, branding should be always done in-house without an agency. There's a misconception that outsourcing marketing is a good idea but often, the outsourced company doesn't know your business as well as you do.

Eric has some great stuff. He and I disagree on getting expert advice, but we agree about being as practical and pragmatic as possible when creating marketing for a new product: http://www.ericschulz.com/1/post/2012/05/make-your-package-s... I love his stuff.
I like the design on your website, but one thing that bothers me is the big red icons on the top right. As soon as the page loaded, I couldn't help putting my eye over there, before I even saw the title.
It felt like I had 3 or 4 facebook notifications I needed to take care of. Maybe it's designed this way to encourage social media use, but I need a chance to look at the page itself before I tweet it out!
Hypothetical musing: what about if the dots appeared once I scroll down to the end of the article?
Thanks BobbyDavid, the icons are an experiment. I've been using DiggDigg (now owned by the team at Buffer) for social sharing but I needed somewhere to put the links to my profiles (not the links to tweet about the content). "Flare" (by the guys who did Tim Ferris's landing pages) is good, but not quite perfect. I'll keep iterating. Thanks!
