I want to code a blog system. What language?

What coding language would I need to learn to code a blog system?
PHP? ASP? What are blog systems (like livejournal, blogger.com, etc) usually coded in?

Why I want to learn coding: to code a dynamic blogging system that supports "categories" (basically, tagging of blog entries), cause I haven't seen one anywhere..

about me: I'm an absolue newbie at coding. Did some HTML back in 1997. (And no..you won't see me post about my mood and what song I'm listening to, so please help!)

>>22-23 same Javur tard

If I did it in Java, I would still be coding the framework, with no work done on everything else. Have you done any real work in Java and a modern scripting language to compare? I did.

No, I mean dozens of different users in my office. Perhaps that's what you're used to have in your Java applications (if you ever write any, and if they ever get completed), but go browse the intarweb, and count the PHP and Perl powered sites vs. Javur enterprise professional applications.
