I was just brainstorming, but with the improved support for video and mp3 in WP 3.6, and the plugins of WPMU (antisplog, analytics multisite and more), is there anything I miss that's a good argument to keep JetPack installed for my customers?
Perhaps one: subscription to new comments and posts under the comment form!
Or does WPMU have a solution for that as well?
Have a nice weekend!!
