I try to collect facts, and to help people do smart decisions based on the facts. Nothing else. I also have a considerable amount invested in Bitcoin, and I run a small Bitcoin business myself. And I do arbitrage between MtGox and other exchanges like most other people posting here.
Yes, and that is a big service in the present circumstances. Of course, Mt. Gox should post estimates on their website and these facts to warn potential sellers. Thanks for gathering this information.
