Twitter turns five years old officially today. I remember when it came out and that I hated it from the start, due to the precious name (it had the groan-inducing title "twttr" originally) and that I rarely used SMS on my clunky t-9 keypad phone. I recall that eventually I gave in sometime in October, and my experience with the still mostly-SMS service was so annoying (my phone woke me up buzzing at 2am when a friend went to Whole Foods and told everyone about it on Twitter) that I couldn't figure out a way to stop the SMS updates and eventually I had to email Biz personally to get it to stop. I found this fun email exchange with Biz and Jack in my Gmail archives:
My friend Eric had put my phone number in as someone to follow even before I signed up so the moment I did, I started getting his replies without any way to shut them off. The texts stopped after this email exchange with Biz, but the experience soured me on the service so much that I didn't return to redo my account until February of 2007.
It's weird that it started off so badly since I've been using it happily ever since. I'm glad they were in it for the long haul, because it wasn't until I got a iPhone in 2007 and custom iPhone apps came around in 2008 that the service really started to shine for me personally.
