Awesome overview of every aspect of the process, it's really a great glimpse into the head of the creator. Also I'm inspired to try the "fuck it" method, I too am usually a perfectionist and thus have shipped very few things.
The hardest part about this entire project took me about an hour to figure out. No, it wasn't sorting. No, it wasn't trying to organize or query search results. It was God damn JavaScript Closures. Believe it or not, out of everything, this took me the longest to figure out. I was close to just saying "Fuck it" and not allowing people to click on links.
Sounds like underscore.js would have cut your development time by more than 25%. You should check it out - it's a great library.
Is this site just Wikipedia search? I only tried a handful of queries, but even very general ones like "google" or "flowers" returned only Wikipedia pages.
