FriendsFlow ($1.99 in the App Catalog) has been around in various incarnations since before there were paid apps, being one of the very first third party Facebook clients for webOS in the homebrew section. Since then, Palm has released its own Facebook App, another third party app called FriendsBook has hit, and Facebook has been updating their mobile site on a consistent basis. So that begs the question: how does the only paid Facebook app in the Catalog stack up against the competition?
