What scripting languages do you have to use to make a social network?

[just "JR"]

(X)HTML, CSS, javascript, php, mysql and AJAX.
AJAX is not really needed, only if you want partial refeshs instead of reloads.
php/mysql are the most common and more eficient than any window version (i.e. asp, jsp, .net), and cheaper to run.

Note: Any hope of getting any kind of social network of the style or type of Facebook, Twitter or Youtube is ludicrous. 1000's of hopefuls dreamers have tried. Many even with good programming experience. NONE ever works (that is, get enough users), unless you have a few 100 thousands of $ to advertise and launch it.

If you want to make a successful social Network, forget FB and the others: HAVE YOUR OWN NEW (and different) IDEA!
Don't be a copy-cat. Too many around.

I receive at least one request a month for these, from people who think they can make it for a few hundreds, and no advertising. I'll just remind you that FB needed $34,000, just to LAUCH FB...
