John Siracusa, on his new site, with a to-do list for Apple for the new year:
Make Messages work correctly. Apple’s iMessage service is rapidly approaching MobileMe levels of undesirable brand association. Fix it in 2013, or be ready for an iCloud-like rebrand/relaunch in 2014.
If nothing else on this list comes true, please, please let Apple make iMessage… you know, work.
