They are doing a fund drive. Definitely a worthwhile cause.
I have just given them US$100. Yes the service is worth many times of this amount to me: quality background info on almost any topic and anything with a touch of the fingertip.
Jasper is starting to ask “WHY”, and I am now all ready for it.
Update (6/10): The results are out. They beat the target by more than US$1K. Well done!
