I find it ambiguous, but on the whole probably a good sign. A negative part is that it appeals to the needy ego. A postive aspect is that it maybe signals a knowledge of the Spolsky school of management, which is a clear improvement over average companies.

But it's not as informative as other signs. For example, programming language choices and transparency. In this regard, the most impressive company I know is Relevance:

Other good companies include Freiheit and RethinkDB:
