Items from old blog added to Google Reader appear as read, want them unread

Question

I recently added an older blog to my Google Reader (it doesn't have any posts within the last year). Because of this all posts show as "read". So, if I browse by viewing "all items", all the posts show. But because they are all "read", I can't hide posts from the view by marking them as "read".

Ideally I would like to be able to mark these old items as "unread" and have a shortcut to mark all of the items in this old feed as "unread".

I see that I can tag individual posts in the feed as "unread". And then I can browse the "unread" tag, and remove individual posts from the tag as I like. The big flaw with this, is that I have to manually mark each post as "unread".

How can I hide posts when everything in a feed is marked as "read"?

Answer 1

Google Reader doesn't allow marking items older than 30 days as unread. Thus, you have only 2 options:

1. Continue with your manual workaround
2. Use a 3rd-party client, such as FeedDemon that syncs with Google Reader and may allow for marking old articles as unread.

As shown in the screenshot below, make sure you have "New Items" selected from the drop-down menu, and NOT "All Items". That way, posts that are marked as "read" are hidden from the feed.
