Nope not related to security at all....
Quoted from opening line of assignment:
"It is not uncommon for us to hear about politicians "twittering".
Is that what they are calling it now? When I was younger, they called it screwing the people.

Just funning with you there, but you also have to watch The Daily Show, which relates, as this is a left leaning show also.
I'd go with a good friend you can trust, do the twitter thing with him/her and make it racy, per hornets idea. I have a gut feeling this is what the prof is looking for anyway, as, like you said, this assignment really has nothing to do with learning computers and how they work both in theory and reality.
Wish they would get back to teaching youngsters how to read, write, and do math again, leave all this touchy feely stuff to others, and teach, not brainwash... <sigh>
