Logos (or icons) shouldn't be taken literally. Pop open your Windows start (or the equivalent for your OS) menu and look at all the icons. How many describe what the app does? For a more concrete example, look at the icons/logos for IE, Firefox, Chrome and Safari. And what about the Adobe apps?
A good logo and/or icon should encapsulate the brand - the feel, the philosophy, the vibe - of an app, and should make it distinct and recognisable. The current icon, while being a little raw, is reminiscent of the black monolith
from Arthur C. Clarke's Space Odyssey series, which is a brilliant association IMO. It has all the right connotations, and is geekily cool, and shares the Sublime look. What could be more perfect? Take a look:http://www.google.co.uk/images?q=black+monolith
Whoever works on the branding of Sublime (IconFactory
would be cool), riffing on the black monolith theme seems like it might be worth considering at least.
