Except in the case of academic literature, RSS feeds can provide information in a very structured and predictable format worth archiving.
I think there is more than a small number of DT3 users who use the software for collecting and searching academic references in various fields.
By the way a separate discussion we had - a feature you indicated is possibly under consideration - would also be of considerable value in curating academic information such as in RSS feeds (see Can Metadata Overview Match Selected Fields Layout - #13 by BLUEFROG ). I think academic users are likely a non-trivial part of your user base.
