Two different programs.
"…To date there have been 72 Shidduchim…" -NASI ad
Apparently there have been at least three different programs, besides for the general awareness campaign.
I don’t think Rechnitz ran out of money…
OTOH, $10,000 is a lot more than the typical $2-3k total shadchanus so if there was abuse, if it led to many shidduchim, why would they shut it down?
So, on second thought, it probably just wasn’t very successful.
