Let me start by acknowledging that Twitter looks useful. I remain one of those who don't get it (I tried), but there are many other things I don't quite understand and in most cases my ignorance is due to my own limitations.
So, Twitter, it's not you, it's me. A few things have been bugging me about you ever since we met -- readers are not sheep to be called followers -- but really, you are cool. We'll remain polite to each other even if entrenched in our respective worldviews. Who knows, maybe we'll do business together one day.
What I can't explain -- nor calmly bear -- is the nauseating giddiness that's been bubbling in my RSS reader for the past year. Everywhere I clicked, it's been twitter this, twitter that. High-school dramas over who tweeted what to whom. (Speaking of 2.0 dramas, here's a great collection.) It was amusing for a couple of months, after which I hoped the spotlight would turn away. It never did, so I thought I'd do something about it myself. Now, everywhere I browse, the words "twitter" and its derivatives are replaced with what the whole thing really is - "madness". All it took was a Greasemonkey Firefox extension and a slightly tweaked profanity filter.
It's like one moment you have hundreds of canaries in your room, and then suddenly someone turns them all off.
It's quieter, and everything makes a lot more sense, too.
