It is a change, yes, and we're glad it's appreciated.
"Uniqueness" is one factor in placement. So is connectedness. It's a combined "score" that is used for placement. The Green, black and red coding is a reflection of that as well. Always has been in fact.
A continuing process of trying to give well run Rings as much positive reinforcement and exposure as possible.
Something else I have noticed which could be a positive thing.
Not all rings are now being listed in the directory. In some categories I have noticed substantial numbers missing.
Is there now a requirement that all rings must be active to actually have a place in the directory? ie. actually receiving traffic.
If so, are you planning the removal from the system of all rings that are proven to be inactive over a predetermined length of time?
