Does anyone know, beyond a shadow of a doubt, whether or not items I mark as shared or starred are permanently archived in my 'Shared Items' and/or 'Starred Items' feeds? I've been using the shared/starred buttons, as well as the new "note in reader" bookmarklet to create what I would hope are permanently archived clippings of things I come across on the web that I would like to keep indefinitely archived, but I am having a difficult time finding out if these items are truly "permanent"...or if I should expect to see my oldest shared/starred/noted items disappear at some point in the future (either when these items disappear from whatever feed I got them from; or if Google has implemented some sort of time-limit or item-limit, after which my shared/starred/noted items will start to be removed). I would really appreciate it if someone could clarify this issue for me once and for all... Thanks so much!
