Personally, I don't like Dave's RSS river of news format. I really don't like reading a list of thousands of new and archived RSS items. It assaults my sense of order. I do like the active bookmarks method for RSS better. In this system, new items are attached to context (the source).I think we are going to find that people divide down the middle on this in a similar way to how people use e-mail. Half of the e-mail users I know let all the e-mail accumulate in the inbox (unsorted). They only focus on the new things and use search to get at the archive. The other half use the inbox as a "hot file" and put older e-mails into an archive directory (for ease of access later). Some advanced users even flow e-mails from some sources using scripts directly to specific folders so the inbox remains "clean." This points to a hybrid solution for RSS. A reader that uses the river of news for an inbox and auto-categorizes the read items for rapid search and retrieval may be THE optimal solution. That way, both types of reading styles get what they want.
