any competent photographers will not feel a threat about this,
we do have our own customers willing to pay our rate for our service,
they hire us is because of our skills, assurance on customers services and quality products
and we don't enjoy servicing a few hundreds of customers, and get paid so little anyway.
for the groupon deal, I guess some, or maybe most of the assignments will be handle by junior photographers later on, as long the deal is still honor, nobody will care that much who is shooting.
the purpose of this thread is we have many junior, freelancers, part-time photographers here, such discussion will help them to get a better picture of how such group-buy deals works, hope they can better do the sum first before jump on the bandwagon.
