Mine does. I also keep a list of people who have IndieWeb sites and most (though not all) will support Webmentions: https://boffosocko.com/about/following/

Most under the IndieWeb and some under the IndieWeb for Education and Blogger headings will support webmentions.

You can find others by browsing through Brid.gy users, the vast majority of whom will support it as will users of Micro.blog. Another good source of discovery is the IndieWeb webring: https://🕸💍.ws.

If you’d like, you can add a Webmention button to your site to visually indicate that you support it.

Update: Also, if you want to meet some “in person”, I’d welcome you to join one of our virtual meetups coming up: https://events.indieweb.org/
