I'd like to launch a bookmarking-like site, but with a difference: People should NOT submit their favorite bookmarks (links), they must be able to submit "feedmarks" -> feeds (rss, atom, etc.) of their favorite sites. It should be a bookmarking service for feeds only.
You can build a) a new project, or b) use pligg and modify it.
1. If based on pligg: Completely unique layout and style.
2. Unique logo and favicon
3. Seo (let's talk about that later)
4. Please show me your references or demos first.
