I think that a lot of specific "keyword" domains are falling out of popularity recently. Take for instance, Thingiverse, Shapeways, Google, etc. Branding a totally unrelated phrase can be just as good as having a specific keyword. For example, Google.com does just fine, whereas Search.com isn't even a website. It's not just about the domain name, and you don't need an expensive domain name to build a web presence.
