Regarding:

The service Jonah and Vipul offer is free. They are doing this for the benefit of the community, not for themselves.

Our offer of free personal advising is for a limited time only. We would like to work on the advising service full time, and so will be charging for our services at some point in the future. Before doing so, we're offering free advising to gain feedback on our service in order to ensure that it's worth the money. We do plan on producing free, openly accessible information: we're writing up our research findings on a wiki which we'll be making public.
