Many blog systems implement the Atom Publishing Protocol (APP).
Recently I found that Blogmarks(a social bookmarking site) implements it too.
I think it would be cool for Pligg have this too.
Some ideas with an app enabled Pligg :
- Filter a news feed by keywords and auto submit to Pligg
- Auto submit Google Alert emails to Pligg
- Add a trigger to a blog system, so that it submits the blog entry to Pligg when it is posted
