“A web-based Excel/database hybrid … Don’t make it feel like a database … You want the database equivalent of a language that makes its easy to keep data in linked lists. (Which means you probably want to write it in one.)”
After I read that, I immediately thought to myself, “I think that guy is talking about Scheme!” Followed closely by, “Wow, does anyone actually embody that combination of talent and insanity?”
But it turns out that Paul Graham, who wrote that list, also wrote books on Lisp, and is therefore exactly the type of person to advocate such an approach. Pretty cool.
