Using Perl to Send Tweets Stored in a MySQL Database to Twitter
Employee_Team +1 Vote Up -0Vote Down

Using twitter can sometimes feel like driving downtown, screaming what you want to say out the window, and hoping someone hears you. There might be tens of thousands of people downtown, but your message will only be heard by a few. Because of this, your best bet is to repeat your message as often as possible.
