Add screen reader feedback for liking, retweeting etc.

[trypsynth]

When favoriting a tweet, or doing other similar actions, screen reader users have no feedback whatsoever if the action was successful. It would be great if either we could have sounds for liking / unliking, retweeting, etc or screen reader speech feedback, using http://www.github.com/dkager/tolk or other similar libraries

[upsilon]

Currently, feedback for liking or retweeting a tweet is provided by the status bar at the bottom of window (same as original version of Tween), but perhaps this is not the better method for screen reader.
So I'm looking for some standard way to announce status changes on Windows Forms such as UIAccessibility.post() on iOS apps or aria-live="polite" in WAI-ARIA.
