Yeah, many people use PHP in web domain as a replacement for Perl CGI. So it's obvious that Kareha/Wakaba were kind of rewritten in PHP.
My other question is why image- and textboard software is so non-innovative. I can assume it's because engines for chans are usually written by amateur and when/if they become pros, they usually don't do opensource anymore.
For example, I want to rewrite Kareha (mode_message) in some language, which is better compatible with UTF8, also make it run under FastCGI instead of CGI. Still haven't chosen the language, because PHP is too ugly, Java is too enterprise and OOP, Ruby is too OOP, Python is too mainstream and I don't like indentation-only, bla-bla-bla.
But I wanted to say, that I don't want to innovate, just stick to the same minimalist, but time-proven principles that introduces Kareha. Of course, I like web minimalist, however, probably partially it's because I am a web dev amateur and it simply would be overhead for me to develop an enterprise-grade web app. Maybe, I would be more innovative, if I had expertise in web dev details how to make an app minimalist, but still innovative, modern, user-friendly.
