Either Joel or Jeff wrote about this in the context of Stack Overflow. A developer who thinks of making Stack Overflow imagines writing SQL:

create table users (id integer autoincrement primary key, username varchar(32), password_hash varbinary(32)); create table questions (id integer autoincrement primary key, user integer references users(id), title varchar(256), body bigtext); create table answers (id integer autoincrement primary key, question integer references questions(id), user integer references users(id), body bigtext);

but actually that's just a tiny fraction of actually making Stack Overflow.
