My friend Niko and I wondered if this method would give any clues like: hi-quality software vs lo-quality, anomalities/ bugs, etc., or whether there is no relation at all. We also wondered if there could be specific code visualizations which would aid the method, other than looking at chunks of text (as text may not be a "proportional" visualization of what the software does, whereas program structure and flow visualizations may be). - Philipp Lenssen
Your blog has a lot of readers, right? You could post a "poll" where you mix a few basic questions about programming language syntax, questions about programming experience, and questions about which source code sample seems better written. See how the answers correlate... - ⓞnor
"Beauty" is kind of a weird metric. Possibly more interesting would be to ask something like "You are making a choice between two equally capable products with comparable specs and features. Given the following code samples from their implementation, which would you buy?" You could ask the question for radiation therapy machines, game consoles, or exercise machines. - ⓞnor
