Looking for a large RSS Feed aggregator

[heywho]

hi, I'm looking for a feed aggregator that I can

• have on a page(s) users can see.
• Organized by categories
• w/ selectable posts
• that --once selected-- Start threads/posts automatically under the category w/ tags
• Indicates that topic has been posted already <forum url>, so blocks reposting

I'd be happy if I could get google reader into a vB page... I've been searching the net tonight for something with feedburner, netNewsWire functionality, (even a service... ) where the sites editors could pick the content from the feeds and post it

I definitely want to hand pick the incoming feeds AND the particular items in each, and don't (necessarily) want one mashup feed coming out --

My intent is to drive community members to multiple sources of content (even content covering the same event) for their own evaluation, and use the forum for discussion of the various views

I can imagine wanting up to several hundred feeds coming in (from NY Times, Reuters, Guardian UK) plus a host of smaller Blogs and range of topics -- hand sorted -- and a maybe 10 or 12 large Feeds --created by user selection of topics of interest and rankings -- going out

I'm not a programmer (soooo not a programmer), but I can certainly imagine this item being useful to others

email me if this exists; someone knows how to do it, or if it can be created

thanks
