Facebook wall writing application
Check out the Facebook API. It will more than likely show that the wall post came from your application. As far as the language you implement in, I think you could use Python.
I was wondering if i could possible write an app, that could be a list of all my friends and just simply posting a message to their walls on the friends i select. Not a message, a wall post. So it appears that i went to their wall and wrote a message, they have no idea that an app is pushing the message to them.
also could it be written in python :) its what i know. php is so icky, but doable if it is the only option.
Please and thank you.
