8% of all online Americans using a website to communicate - that is an extremely significant number. I wouldn't use the word "only" in that sentence. Not only that, but many out of that 8% are very influential.
It's very clear that Twitter is a cultural nexus right now. That's why search engines are doing so much with it. Many large enterprises are finding Twitter crucial - and they're willing to pay 6 figures annually for the market intelligence that can be extracted.
There's another thread in this forum that at least starts to scratch the surface of Twitter's value for the SMB, too: Why should you use Twitter? [webmasterworld.com].
