There are obvious answers (like it is easier), but for a technology as dominant as the web, these are surprisingly superficial.

An analogous example is indexes in database technologies. They add a lot of implementation complexity, but are paramount for optimizing for "reads". What would a web framework look like that optimizes for "reads" instead of "writes"?
