Honestly, I set up webmentions to use brid.gy, not just for the sake of using webmentions. I wanted a two-way integration between my static blog and Twitter, and this solution has done the job nicely.
That I ended up with direct webmention support was just a bonus as far as I'm concerned.
Correct. Using the right microformats, it'll auto syndicate notes as tweets and full posts as tweets with a summary and a link. All my site has to do is shoot out a webmention to brid.gy and it does the rest.
Then when people react (reply, like, etc) it'll proxy those interactions back as webmentions.
