Zero, zip, nada unless they can figure out a way to stop all the back stabbing attacks that are currently allowed & many of the features that @KNOWITALL listed.
This question made me notice the Fluther mug I have on my collectible shelf. And made me think about those Fluther mugs I sent as gifts to several jellies years ago. Now if only I can remember their names.
To answer the OP, right now the amount of money I could pay for Fluther’s monthly fee would just be too insulting to this awesome site to reveal. If and when better times come I would pay 30 bucks a month.
@mazingerz88 You sent me a Fluther mug with my former name, jonsblond. I’ve been using it until yesterday when it fell and the bottom broke in pieces. I cried. :(
