First, most existing lists have been created to serve particular constituencies in particular ways. These two lists would have a vast quantity of information, most of which would not be of interest to any particular individual or group. Every individual or group could contribute and could download and repost any material which seems useful or inspiring. Second, the sheer quantity of information would put a burden upon all those whose Net connection is difficult or costly. They would not want to pay for the connect time to download great quantities of information for which they have no immediate use.

The idea here is that individuals and groups are likely to find some threads of discussion or sequences of information on particular topics to be worthy of particular attention. If they have their own web sites they could download and prepare such collections and introductions and then merely have a hot link installed on the RICA web page.
