Important Notice
Virtually all of the funtionality from this stackapp has since been incorporated into Stack Exchange natively since it was developed. As a result, this app serves no real purpose and is just kept here for historical purposes. It will probably not be of any use to anyone any more.

About
I know there's already at least one other aggregator out there, but I wanted to have a go at doing my own anyway.
The graphing realllllly sucks, and not all the functionality is avaliable, and there's probably bugs, but I did it as an exercise to rehash my programming skills.
License
I probably broke a whole bunch of rules because I nicked the stylesheet straight from ServerFault. If this is not cool, if someone from the team lets me know I'll change it ASAP (Actually I plan on changing it soon anyway).

http://sagg.column80.com/ - I've pre-programmed a bunch of sites into the list of avaliable apps, but you can add your own by entering the domain name (e.g. All of the API exposed sites are automagically populated (cached every 24 hours), but if you want to add your own API exposed site, then you can add it manually (perhaps a unicorn told you about a new site that's not in the official API list but still runs the API?)meta.stackoverflow.com) on the configuration screen.

Code
I haven't done any programming in about 5 years, so it was also a way for me refresh my skills. It uses the PHPStack by Thomas McDonald. If you really want the source and you promise not to make (public) fun of me, then I'd be more than happy to share.
It also gives easy access to:
- StackTack by Soviut to give users easy-access to pinning the question onto their own pages.
- StackPrinter by systempuntoout for a nice Printer Friendly view
- Analytics Overflow by Nathan Reed for tag stats (accurate for SO only)
