Looking for news/newswire/link-sharing plugin (like facebook post to timeline)

Dear all,

I’m looking for a plugin that will automate the process of posting links gathered from around the web — just like Facebook’s “post to timeline” feature which automatically extracts the post title and a blurb.

Ideally I need this for two things: breaking news for a news wire widget, and a more general “More about this topic from around the web” page that contributors can easily update.

I can’t find this in the extensive plugin repository because I’m not sure what to search for. Everything I try comes back with dozens of pages of irrelevent results.

Thanks in advance.
