I am twitterpated with twitter. Ok so that is a bit strong but for some reason I am addicted to twitter. What is twitter? Well think of MSN messenger and AOL messenger mashed up with your favorite forum and walla! So what is so cool with it? Not sure. I mean to the untrained eye it looks like a bunch of people posting about what they are doing as if someone gives a ________ (enter favorite word here). It just happens to be that you invite friends to watch and listen to your tweets! Once again twitter jargon. Bad Bad Bad! I know. 
In case you want to join me or listen to more ranting (wow his blog isn't enough? you ask.) My username is much like my domain name (in case you are not sure where you are in the Internet meta - universe. (mikedopp or mikedopp.com)). Here are a few of my favorite little applications to keep up on your twitter browsing or activity and be warned it is addicting and I am not sure why.
