Scribd, dubbed “YouTube for documents” didn’t have the the traditional dip in traffic after its launch, and has continued to grow rapidly after raising nearly $4 million in two rounds of venture capital.

I looks like they already have competition, though. I’ve been hearing good things about new startup Docstoc, which is currently in private beta. I haven’t been able to get in and see the service, but others that have are telling me its pretty cool. The video above shows an early interface, which I grabbed from the Docstoc blog.
