webapp & concurrency

ちょっと目から鱗な気分。

you can certainly build a webapp without using concurrency features directly. Most web developers don't. Just keep in mind that most framework designers use languages that support concurrency so poorly, that they have resorted to fooling you into thinking that the only webapps you can realistically build must follow the good ol' request-response, single-threaded, CRUD-based paradigm.

This is clearly a fallacy.

Many high-quality, innovative webapps don't follow this paradigm.

The Google search engine doesn't follow this paradigm. Neither does Meebo.

Many of the great webapps of tomorrow won't follow this paradigm.
