News Aggregators - RSS Feeds

Anyone a guru when it comes to this?

I’m looking at creating a site that ideally I would like to have serve as a sort of “portal” for lack of a better term. I would like to scrape as many news items from as many sources as I can that pertain to a very small niche idea and small geographic area.

I’ve had a bit of a play with google news widgets etc and they seem decent enough but would like to know of other methods that someone has experience with as well.

Ideally these feeds would “show” the content on the site so the site can benefit from SEO and searches etc.

Hope someone can clue me in on this… extremely grateful for any help.
