In reply to Peter Knight (@peterrknight).

That's the primary one. There's lots of little things I don't see a need for (such as Press This Post via Email, and the calendar widget, but that's a discussion for another post), but again, the Jetpack commenting feature is much better than default WP and it makes sense to me to remove it from core and setup as a standalone plugin. It was only a few years ago that Links were removed from core and placed into a plugin.

Not sure what you're referring to in regards to photoblogs and the text editor.
