I'm very sorry to say that but the whole thing looks like my browser is accidentally zoomed out to 60% or something like that. I still belief that the actual written words are the most important thing in everything we do, may it be an encyclopedia or an issue tracker. Reading these words is the number 1 task. I don't want everybody who visits our issue tracker to search for her/his glasses or fiddle with the zoom before she/he can start contributing.
A comment below notes: Phabricator's font-size does NOT depend on the configured default font size in your browser. it should.
