Movable Type or Wordpress plugin to publish content from other blogs automatically on my site?

I'd like to build a plugin where a WordPress user (or other platform like Movable Type) can install and publish automatically in his/her blog and at the same time to my website..

This is something like Facebook already does... I have no clue where to start with or if there is already any pay service I can use instead... If you have any documentation to sugge开发者_StackOverflow社区st I'll appreciate it...

Have you looked at the Movable Type plugin called Reblog? We use this plugin extensively to republish content from other websites that's exposed in an RSS or Atom feed.

Movable Type and Melody can do this, depending on how you want to do it. In some cases, it'd require a plugin, but if you manage both sites with Movable Type or Melody, you can have an entry on one site appear on the main page of another.

ReBlog is a very old, but still nice solution that I've used myself in the early 2000 years.

Alternatives to it, are the following other solutions:

1) for movable type v4.x and v5.x http://en.magicvox.net/archive/2010/04110959/

2) for movable type v4.x (not tested on v5.x) https://github.com/danwolfgang/movabletype-crossposter

There is one more plugin, but that works with v2.x which is very old.

This is just as simple as having that second site subscribe to and watch for updates to the first's RSS feed. Whenever it sees an update, it sucks it down and re-publishes it.
