Deatils?
How does something like that affect us, the users of the forum? We do not pay to use it, so there is no anticipated "passing the cost to consumer" scenario. The owners must be compensated based on the advertising revenues generated through ads combined with the total viewer numbers.
Also if the cost is 2K/yr and it went to 4, so what? Doesn't seem like a lot. Or is it 30K and gone to 60? That would be a lot. Could it be a million going to two? I think it is all relative and should be viewed as part of the overall business model picture. In itself it does not seem to have much meaning.
