Do you know market share for OS Commerce, Magento, Volusion, etc?

Hello,
We are wondering what platforms most people use. We are building plugins for our store search software for online stores. We built one for Magento, another for a platform called Oxid out of Germany, but OS Commerce, Volusion, etc? How many users do they have?

Can you answer a quick poll to say which one you think has the largest install base of active shops?

Thanks,
Dan

That’s right Ecommerce guy but I don’t believe they \have a scheme to allow 3rd party plugins, do they?

thanks for this bluedreamer!

You should add ProStores to your list - the hosted, off-eBay, ecommerce solution from eBay.
