With this script you can open the unread items of a selected feed in Vienna in either Safari (on per tab) or your default browser. Additionally the script will mark all unread items as read in your selected feed.

Open Vienna, select your feed you want to read and run this script. If you're using Safari you'll need to activate "Enable access for assistive devices" in the Universal Access preference pane (if you haven't already done so). If you're using a browser other than safari you can change 

openFeedInSafari(theURL)

to 

openFeed(theURL)

in line 18.

In order to run this script more elegantly than double-click it from Finder you may prefer to run it from scriptmenu
