Michael Heilemann talking about Twitter’s latest API changes and, more specifically, the news it killed it’s Mac client:

It may take years, but if it really is Twitter’s intent to kill the desktop client, it will definitively mark the end of my use of the service. The API changes hurt me on principle, but killing the desktop clients actually hurts my practical use of Twitter as a service. Most days I’ll have the client open on my secondary monitor and occasionally glance at the stream to see what’s going on out in the world as I work. Contrast with Facebook, which I open maybe twice a day unless I specifically receive a notification.

Which do you think I interact with more often?

Since I only have a single screen, Twitter is off to the side but always open. It’s my secondary way of getting things to read and my primary source for news. Facebook get’s checked three to four times a day if you include any chance I might have in the morning and in the evening.

If the desktop client – or all Twitter desktop clients – go away, so will I. App.Net is looking pretty cheap right about now.
