Logo's alt text is not appropriate for its context

An image of four circles next to the site's name would take guess work in order to understand. IMHO a more appropriate alternative text representation for the logo should include the word logo, but in this case the logo does not convey any information other than visual decoration so the alt text could also very well be empty.
