Team Fortress 2 Workshop went live on October 13, 2011 - 3,571 mods
Skyrim Workshop went live two days ago - 1,123 mods
At this rate, we'll see double that by next Tuesday, 5,000 in two weeks, and 10,000 in a month. Valve need to clean the place up quickly or it's going to be impossible for new, high quality mods to get any attention. Not only that, but it will be compounded by mod authors unable to find equivalent mods before developing their own version.
We can take solace knowing the content from the uncommitted and amateur modders will come out in that first month. After that, there won't be nearly as much redundant trash and the workshop will be tolerable again. In the meantime, I'm avoiding it. The Nexus is still the way to go if you care at all about quality, useability, and organization. And remember this: Most of the people using the CK right now know only of the Skyrim Workshop and not of Skyrim Nexus.
