I actually thought it was interesting/relatively nice that it automatically pulled the three photos and laid them out that way, but in that case I'd have done higher res photos for better clarity. The "indieweb mini-logo" is a really small icon way down in the footer of my page and I was most shocked that it popped up on the post.

I typically have been using SNAP for POSSE, but as I've been watching your work recently, I felt compelled to test out Bridgy Publish to give you some feedback about UX/UI as well as bang on things for bugs in general.
