While I suppose I can understand your first argument, I don't see much problem with the candidates being hand-picked. If somebody is "not extremely active" in the community, why would they be selected? Obviously there is a heavy workload imposed upon the judges, so why should those who are partially inactive be selected? From what I've observed, those who have their hands in shaping the community become possibilities for judges.
Pixietricks, for example, has done and continues to do much for OCR. It is of no surprise to me that she is a judge, because she's clearly demonstrated that she is both a worthy and wise choice for the job.
I'm not entirely sure what post counts have to do with this argument, and your example of BGC seems rather contradictory. The selection method of judges is flawed because they may too readily pick a better-known name over one who is more worthy of the title, but happens to remain in the shadows; and yet, BGC is an example of this flawed system, because nobody knew who he was?
I'm afraid I really don't follow you here. I think the selection of BGC as a judge very clearly disperses the accusations of bias in judge selections, as he was selected without being a well-known ReMixer.
And personally, I love both Pixie's and BGC's stuff.
