Pluck RSS Reader: Retrieve news from favorite sites

Pluck RSS ReaderAnother RSS reader, this one an IE plug-in. RSS seem clients now come in four flavors:

1. web service/asp: use browser to work with
2. email plug-in, esp. Outlook
3. browser plug-in, esp. IE/FireFox
4. standalone

I think the standalone are unlikely to go too far. I'd like to use a web service that had companion plug-ins for Outlook and FireFox, so they'd share a single OPML file.
