In doing some research on the HOA (more on that later), we stumbled across a few resources that are starting to come about for this new Mueller community.
The Mueller Redevelopment Yahoo Group - a pretty active discussion list with lots of members (presumably, many or most of them are folks in surrounding neighborhoods; Jim Walker, the head of the local neighborhood alliance that was integral in the early planning stages from Mueller, is a frequent poster.)
Design & The Car Dependent City - A blog by an Austinite that talks a lot about urban planning in general, and Mueller specifically.
Flickr Photo Pool - An ongoing pool of photos of and about the Mueller redevelopment, started by Prentis Riddle. (Some really beautiful photography, too!) The photo at right was taken by Flickr user mirsasha. We'll use photos from that stream here whenever the license allows (go Creative Commons!) to make this blog a little easier on the eyes.
I'm sure there will be many more like these to come, but these are the first crop. There are lots of local real estate blogs that mention Mueller as well, but I'm sure you can find those on your own. :)
