@LorenzoAncora @tennoseremel @quasi @lxo >the JS-less approach works well until the number of web requests grows.
Considering that fastCGI uses less web requests that your typical JavaScript webpage (it gets everything done in one hit fast, rather than keeping a socket open, or multiple to perform each operation), JavaScript scales worse than fastCGI.

>keep the user experience smooth and keep out the bots and AI through PoW captchas.
Scraping bots can be detected by analyzing the access logs and then you just block them (usually fully automatic, as they hit the server multiple times a second from the same IP or IP block).

PoW captchas written in JavaScript burn a serious amount of electricity and why wouldn't advanced scraping bots just run the JavaScript?

>cloud integration with file hosting
There is no cloud, there is only someone else's computer.

>Those things only scale well with JavaScript.
JavaScript doesn't scale well due to its poor efficiency, although most webhosts don't care about dumping the inefficiency onto the suckers.
