According to DestroyToday the bug in Adobe Air which prevents spaces from appearing if you type Shift-Space will be fixed in the next release, though currently there is no timeframe for this new version.

I will be glad to see this fix as I use DestroyTwitter Twitter client which runs under Adobe Air and I am really fed up of sending Tweets with missing spaces…

Over on What The Lemur W. Thomas Leroux has a small Applescript that will post the currently playing iTunes track to Twitter so your friends and followers can see what you are listening to. All you have to do is cut and paste the code shown into Script Editor and edit in your Twitter username and password then save as an Application and run it. The script loops through every 3 minutes and if the current track is different to the one playing 3 minutes ago it posts a new Tweet, so obviously if your current track is very short it may be missed.
