What would we do with the services that have Both Paid and Free Services. Separating the two services could get annoying for the person running the service.
Additionally, the way of ranking the quality of the service is by seeing how many vouches and sales the original poster has. Thats the only way to do it. Having a whole system built in on how to rank the quality would be too time consuming and unnecessary.
Some services will have perks that others will not, so it all depends on what the user is looking for.
Otherwise, it was a good suggestion but I dont think it is necessary. Especially when the Free and Paid services mostly use tags like [Free/Paid] and stuff like that.
Thoughts?
