In RawSugar each tag bundle or folder of tags has its own URL…this is great as you can view the latest bookmarks within a set of tags, this is a River of News topic stream.
It’s like splicing several feeds into a merged feed, and presenting it into a topic stream.
The beauty of it is that within the one account you can have multiple topic streams, one for each tag bundle/folder.
The difference between this and traditional newsmastering is that you are populating the contents of this portal via collecting bookmarks, it’s not being automatically populated by someone else’s feeds…the only type of feeds allowed in your RawSugar account are RawSugar feeds.
Each tag in your topic stream has a feed, and the whole topic has a spliced feed
…each topic could have an OPML URL Reading List
Your whole account has a feed, therefore your whole account could have a mega OPML URL Reading List (made from each topic OPML URL)
For other types of Newsmastering see SuprGlu, Blogdigger Groups, MySyndicaat, etc…
