Twitter is nice and DRY.  No more of all those java SCRIPTS that hourglass IE8.  Feb 2013 started as some sort of Video Game - in editing posts - in the Twitter Box where every action tossed the cursor to the end of char string!?!?!?!

This last week of Feb.2013 the above “editGaming” seems All Cleared Up :-)
