Originally, I came to 5r for micro work, something fast and quick. If I needed a short story proofread or edited, a quick translation for a book blurb into any language, etc., 5r was the place to come. It was fast, the process was easy and the sellers gave me great work.
Nowadays, I find myself doing more complicated projects on 5r. I am putting together a site that requires more technical and time-consuming work. I need complicated articles and blogs written, animation/graphic artwork for specific nitch to fit website/blog/community.
I have great deal of confidence in the abilities of 5r sellers to deliver exactly what I want. The problem is that before I shell out hundreds or several, I want to consult with them to see if they are the right fit.
Right consulting take time and time is money. If the sellers had a tip jar/consultation gig, I can use it to buy your time. I pay you $5 or $10 to give you what I need and how I want it done, you give your response. If we are the right fit, I can order; if not, you were somewhat compensated for your time.
If you offer a complicated service such as high tech web design, artwork, etc. it may be in your best interest to have one of these gigs. Even if you do not have a complex gig, occasionally, a repeat buyer, for the goodness of their heart, want to give you a Crhistmas present. I mean a tip gig is free money, so what have you got to lose?
