del.icio.us filtered is a way to filter out seeing the same bookmark again and again in your RSS reader (which can be very frustrating).
It would be good if I could run my 10 Yahoo! News and 10 Google News RSS feeds through a filter and generate a “No duplicates RSS feed”…anyone!
…or can this be done within the RSS Reader, sometimes I’ve noticed that an item in Newsgator Online has a duplicates link (not sure what this means).
NOTE: there is duplication anyway due to different newspapers re-syndicating the same stories…although I think Google News tries to collapse these items.
