At first I wasn't sure who the target market for this addition to the Google repetoire would be.  

• Seemed that anyone who knows basic web design would find it frustrating/limiting.  
• Seemed anyone who didn't know basic web design would be frustrated for opposite reasons.

Actually, now trying to use it, it seems like a fast and dirty way to get content up without having to think about it.  It's potentially more straight forward than blogging when it comes to wanting to play with including images and not being forced to have a chronologically organized site.  

I still haven't played around enough to see how flexible it is when you know what you're doing and you want to be able to polish it up. 

I'll let you know what I think when I find the time to play around.
