great post, thanks for writing it! and the screenshots are especially helpful. nice work!
a few minor additions: * Bridgy will happily send interactions from Google+ and Instagram to Known as well as from Facebook and Twitter. Known can’t copy your posts to G+ and IG automatically (afaik), so you have to do it manually, but otherwise they work the same way. * along with Facebook likes and comments, Bridgy also sends RSVPS and comments on events. * you can make Bridgy send interactions to additional web sites by including links to your original posts on those sites inside your tweets and Facebook posts.
thanks again!
