It looks like those of us using the WordPress for iOS app will soon be able to respond back to comments without having to install CommentPush.
Push notifications are coming along nicely! [...]
According to Chris Boyd users would be able to visit the exact comment posted upon your blog from within your app which is similar to how Twitter for iOS sends users to the exact Tweet reply instead of merely opening the app.
This will make it not only much easier to reply back to comments in a timely fashion, but also help weed out human spam much faster.
As far as push notifications for likes goes, hopefully WordPress has a setting where users can turn this specific feature off as some blogs may receive hundreds of likes in a post (note: push notifications for likes is only available for WP.com sites).
This future update should also help WordPress stay competative against rivals, especially Squarespace (the latter which has boasted push notifications for several months now).
Note: Yes I know the WordPress app icon is upside down, but that was apparently done so the team could distinguish between the test app and the one approved by Steve Jobs app tribunal.
