Thank you for your comment. Would you prefer to be rated by an authoritative source using inputs that are closed and unknown? Or, would you rather have your peers provide a rating in an open and transparent manner?
[I think] Crowdsourced opinions are an excellent way to make informed decisions about products/services. A great example is using Amazon.com for competing products:
Product A: 5.0 star rating | 32 reviews
Product B: 4.5 star rating | 5,264 reviews
Which product would you weigh more heavily when making a buying decision?
Keep in mind that SELLFF is positioned as a Professional Network. Any response or feedback will be relative to you, in a professional capacity. This might include the quality of the service you provide, your communication skills, did you finish the job on time, etc.
Also, any reputation you earn as a seller works in your benefit when you consult with others as a buyer. People want to work with other people who they have confidence in. This is true on Uber,Lyft and AirBnB, where both parties "rate" each other.
I think a digital reputation is a vital part of a healthy marketplace.
If you crowdsource reputation, people will be able to buy it.
