Some people don’t seem to like Google Base – I like it a lot and I’m sure that its a product that will gradually evolve into something truly revolutionary.
So far nobody has been able to touch Ebay, but one gets the impression that since they are an effective monopoly Ebay have become very conservative with their product, not wanting to risk innovation which could mess things up.
This leaves others who innovate with an opportunity, and Google will innovate here.
The people that pay Ebay – the sellers, would switch if they could, but Ebay has the buyers. Only someone like Google could offer a rival marketplace of buyers.
As an aside – since the single item Google Base upload allows you to define your own metadata via custom name-value pairs, does that mean that with bulk uploading Google will intelligently parse RSS modules in their own namespaces?
If this is the case then RSS has taken one mighty leap forward.
