This means that there’s no longer a conversational element to Twitter while I’m away from my desk; it’s no longer any more useful to me than email / blogs.
Without the conversation, Twitter is just, um, a website, it’s no longer a communication tool for me.
Plus, (sorry but this is a fact) Twitter will just be a USA dominated thing now; there’s no room for Europeans and Australasians any more.
I shall stop promoting Twitter to my friends, and it will become ‘just another’ web thing to me.
Sad, sad day.
Update July 2009
Since I wrote this post (which gained some notoriety) I have bought an iPhone, and such apps as Tweet Deck and Twiterlator have helped me keep up with all my friends and followers in a very pleasant manner.
Further, I believe that both Vodafone and now O2 in the UK send tweets via SMS again – so there’s been real progress in the last 12 months since Biz’s announcement in 2008.
