Script Summary: Remove all stars from visible Google Reader items for particular tags
Google Reader Kill Stars For Tags will unstar entry in Google Reader which match a particular tag. To make the script work properly for you, you will need to edit the source code to insert the item tags that you want to unstar. Look at lines 14-17:
var unStarThisTag = [
This is the list of item tags you want unstarred. Change the current tags to your preferred tags, placing each tag in quote and ending each line with a comma, except for the last tag line. The script will loop through each tag for each Google Reader item, attempting to match it to existing tags for that item. If successful, it will remove the star for the entry.
An important restriction is that you must be in expanded view when running the script. Unfortunately, list view does not contain the tag information and the script cannot work without that information. Also, remember that only items which are loaded into the pane will be processed, Google Reader Kill Stars For Tags cannot process entries which have not been loaded.
This script is dependent on the internals of Google Reader and future changes by Google or untested browser configurations may prove problematic.
