I have found Sales have been awful for the last couple of Months on all sites .. not just for Footage but after effects Templates as well ..

According to User Poll IS has also come up near the bottom for Sales as well this month

I also couldn't consider going exclusive anywhere either and relying on One site to make an income

and Zerkalo

Some people don't have enough time for spreading their portfolio on other sites.

Its much easier to spread the portfolio around with something like Picworkflow .. upload once and spread it around with a single click .. by the time you get home from work your footage is on all sites .. copy and paste in keywords and done .. it everywhere

I have done a Up to Date list of Places to Sell if it helps anybody or if anybody can see shich Stock Sites are missed of the list http://www.stockproducer.com/selling-resources/where-to-sell.html

I Also uploaded a few clips ages ago .. but never had a sale .. don't even check there any-more
