BuddyPress.org

All titles for the top level pages /groups /members /blogs and all blog posts are “Blog Title” out of the box.

Members pages are titled “Member >> Profile >> Public” w/out blog title.

And Groups are “Groups >> Example […]” w/out blog title.

Titles being highly visible and important in seo… this is about as bad as it could be. These pages are probably not where you will drive traffic, but they are prominently linked, and not anywhere near optimized out of the box.
