I've got an idea that would probably differentiate online-tipjar from the other tip sites.
This may sound a bit odd but I personally would love to have a way to tip the actors in porn films. I like porn but feel terribly guilty about the actors being exploited. I wish there was a way to redress this (because I really don't want to give up the porn!). I would like (and hopefully other people would too) to be able to show my appreciation to them. They bring hapiness to us; they should
be appreciated. That's what I think, anyway.
Potentially, tippers would tip stars more than once for the same performance (if it's one they go back to), so it would hopefully balance out the fact that they don't get royalties a little bit.
I guess the people you've already got signed up with tipjars perhaps wouldn't be keen on being associated with adult entertainment so maybe an easily found dedicated sister site would be the way to implement this.
Well, what do you think? I hope I've sold it well enough because it is something I sincerely believe in.
