CBF is a bit like a life manual and like any life manual I guess it depends how often you want to dip into it. Some might only want a little info, others much more. And like a life manual sometimes because it is there it is a comfort, even if you no longer feel the need to dip into it.
CBF can save you money, save you time. It can help you make the right decision and help you avoid making the wrong one. It can improve you health and it can make you a laugh. It can prevent feelings of isolation and being alone. I think GOOGLE refer to the value of having a virtual community but one gets a sense that there is a real community as well.
Of course somethings it does better than others. Perhaps it is not quite as good as promoting the Turkish culture. Some might say it is parochial, though I would not agree. Perhaps lately the contribution from women has been less dominant than before, which is a bad thing, if true.
Overall I find it a really helpful and informative resource and would miss it if it was not there.
If the number of hits is a quality indicator then it is doing well and is healthy.
