When you have the list of blog posts on your screen, that's the current "page".
If your browser (not ATP, but your browsing program) has a menu bar, or buttons, try looking under "edit" or "search" or "find". The perfect option would say something like "find on this page".
The closest thing I can think of inside ATP, to what you're suggesting, is the "Memberlist". At the very bottom of many ATP pages, there are small links including "Memberlist".
You could go there, browse member names alphabetically, jump to their public profile, and from there to their blog posts.
