I know that I should be practicing BDD, and normally I do, but for this site I'm writing specs after the fact. BDD/TDD are awesome concepts and can be useful design tools, but they are somewhat useless when you are creating something without any upfront specs. Frankly, I started this site just by playing - to see what I liked and what I didn't. So now that it's at the barebones stage and I feel comfortable that what is here won't change much, I'm going to start writing specs. Going forward, as I think of new features that I'd like to add, I'll likely go at their creation from a BSS perspective.
