Oh, it's wonderful. Nothing but praise for those guys.

Like a profesh Wayback Machine or something.

It listens for my publications across all outlets and republishes them (+backlink to original) there. Plus sends me (and subscribers) notification email when new material. If original outlet takes it down or changes URL or deletes their history, I still have them up.

I basically used to pdf versions of my published work before so that I would keep a record, and this does it automatically.
