Cruise over to href="http://feeds.scripting.com">feeds.scripting.com and check
out his new hack of sharing/aggregating/exploring of OPMLs (aka XML
formatted list of RSS/XML/RDF/etc feeds)
If you are using AmphetaDesk, go
to the 'Coffee Mug Prefs' section and change the template to be this:
http://127.0.0.1:8888/index.html?add_url=[[xmlUrl]]
and you can just click on the coffee mug and have it automatically
added to *your* AmphetaDesk OPML.
