Imagine how I feel. It's really just the same as before except everything is different. You know how every now and then you go to the grocery store only to find they've rearranged all the products in an attempt to increase impulse sales due to everybody having to run around looking for what they need? The same thing applies here, except there's no reason for it.
Eh, you kind of have to give it a chance. Click around and find out where things are, before trying to just jump back into asking and answering questions and such. After a while it just becomes a matter of getting used to how large and spread out everything seems to feel.
