Got a web site?

Want to publish your posts to social networks?

Want to see comments and likes on your site?

Bridgy is for you.

more – from your own web site. It also pulls other people’s comments, likes, and
reshares of your posts back to your site. In
IndieWeb lingo, Bridgy lets you
POSSE to
the silos easily and
backfeed the responses
automatically.

This looks like a really exciting development in social media. Recently most of the commentary on blog posts has moved to twitter, g+ or facebook. This looks like it could link that up and push out posts and then pull comments made on other sites back to your blog.
