I just successfully connected my WordPress account to Twitter. I don’t now how this works yet but WordPress says “You have successfully connected your WordPress.com blog with your Twitter account.”
But Twitter is a really amazing web technology. Almost anyone with the slightest programming knowledge can easily use the API to create new Technologies. I have created a few myself in Flash, PHP, C++ and using shell scripting. There are assorted frameworks too that make life much easier when making a playing with Twitter. So, pick one of them and start making dreams come true people.
