I am sure it's been suggested before, but rather than a gig independent of itself, why not provide a feature that after a gig is finished the buyer has an option to tip the seller any amount they feel the seller deserves. I am thinking of it like this.
Let's say the person buys a Fiverr gig, afterwards they leave positive feedback. After leaving positive feedback, a notification comes up or a drop-down menu of sorts comes up asking the buyer if they really liked the work, if they would want to tip the user a little extra for their hard work.
To go a little further, maybe even something that appears underneath the particular positive feedback of the tipper saying something along the lines of, "tipped for an exceptionally good job!"
