I don't know much about the site Online MBA, but I enjoy their infographics.
Their most recent infographic describes the history of Groupon and how it works. Lately we've been using the word "epic" to describe Groupon's growth. We're doing this because words like fast, enormous, explosive and amazing don't seem to good enough.
Whatever you call it, Groupon's growth is nicely explained by the inforgraphic.
BTW, not everyone thinks Groupon and discounting is good for small businesses. Branding expert Laura Ries presents this point of view in her article Coupons, Groupons and Cocaine.
The 2nd topic of this post is the power of good content.
We get lots of people offering Smallbizlabs money in exchange for paid links and/or coverage. The main reason they do this is search engine optimization (SEO). We have a decent Google page rank and links from our site help with SEO programs. Our policy is not to accept these.
Online MBA has effectively gotten around our policy by creating compelling content. They've earned the 3 links (retail value = hundreds of dollars) in this article by providing information we think our readers will find useful.
That's the power of good content.
