I have the meta tag name="robots" content="noarchive stuff in the blog HTML code which prevents search engines from storing the page, they only index it. Is there a way to do something similar in case of web-based RSS readers like Google Reader?
Something like they read the feed and show the items for the subscribers, but the entries expire after, say, 2 weeks and they don't show up in Google Reader archive search anymore (Reader and similar services normally stores old items). Is it possible?
