Even though Google is making strides to lessen the importance of domain names have on organic rankings, it still matters. Sometimes it matters a lot. In a different industry, I picked an exact match domain for the most searched term in my area. The equivalent in this industry would have been "lawn care springfield IL." Within two weeks I had the top organic placement on Yahoo, Bing, and 2nd page of Google. After a few more weeks of link building, content writing, etc., I'm now fifth organically on the 1st page of Google (outside of the local six pack as I don't want to rank there for certain reasons). So to summarize, even though it is becoming less important, exact match domain names still do alter rankings (especially on Bing and Yahoo which account for around 18% of search traffic from what I've read).
