It is my opinion that this is not a good idea if used as a criteria for Monk limitation of any sort. Maybe an accompanying comment to the author when a -- is given is appropriate and even replacing ++ && -- with a vote of -7 .. +8 would be great but my problem with this idea is this: sometimes each of us posts or replies on an obscure topic. These ones don't make the Gates and therefore don't get visited as frequently. They're much less likely to be seen to receive votes at all. That doesn't mean that they're poor posts or replies though.
Certain Monks have advocated a recent average requirement to post new or awarding extra XP (which is redundant if you're already excelling in that department to achieve such a level) if a high average is maintained. These would primarily weigh towards anything landing in the Gates but that's not fair since many obscure posts are just as valuable and informative even if they aren't seen by everyone. Also, the Gates only holds like 4 SOPW posts at a time and the turnover will be great when many good SOPW posts are made in a short period of time. Meditations persist much longer and therefore, routinely achieve massively inflated valuations. I just don't think these statistics should be used to limit access or anything. If they're solely for informative purposes, I don't see any harm. TTFN & Shalom.
