Automattic isn’t leaving self-hosted, WordPress.org users in the cold, though. The new interface is also available for users that have Automattic’s Jetpack plugin installed.
They’re also releasing a WordPress admin app for OS X with plans for Windows and Linux versions in the future.
I’m not a Jetpack user, so I haven’t had the opportunity to try out the new interface. I also haven’t touched my MacBook Air in days, so naturally I haven’t tried the OS X app, either. But I don’t expect I’ll be doing so anytime soon. I’m already pefectly fine with WordPress’ current interface — it’s grown on me over the nine or ten years that I’ve used it. And I just don’t do that much writing on OS X these days. The vast majority of my writing is done in WordPress’ Press This bookmarklet or in Vesper on iPhone or iPad. The workflows I’ve fine-tuned are comfortable and there’s no need to introduce new software that could slow me down or break things.
At least for now, I’ll be sticking with WordPress’ current, PHP interface and the applications that I already use for writing.
