Already so few people seem to use this feature, so charging FG for more pages seems a bit miserly. I mean... it's just a blank page of digital notpad, the type everybody has on their computer and might as well use instead. It couldn't even be argued that it adds to the ''value'' of your profile as media slots / friends slots (supposedly) do, since it's visible only to yourself.
Well, other than that I like all of your suggestions.
