Dropbox: The hottest startup you've never heard of
I think this article is perfectly valid.  What everyone here is forgetting is that we are a pretty focused demographic of technical people.  If you ask the average CNN user what Dropbox is you'll probably get a blank stare.  The fact that an article like this is BEING written is just another sign of Dropbox's success... it may be crossing the tipping point to main-stream media and adoption outside of the tech community.  I bet if you looked you would have found something similar about Twitter at some point where social media savvy people were going "WTF?  I've used it forever"
