@max @bastianallgeier it’s funny; my Twitter account is from Jan ‘07 (and only because I waffled for a few months) but I don’t think I *ever* used the SMS gateway.
I did use Twitterriffic* extremely early on long before anyone knew what a hashtag was. We would also say twoosh! when we hit exactly 140 chars.
* I also did some method-swizzling to add my own enhancements, called Twittereeze. My marketing head has since been fired.
