Lots of changes are happening with UX Zeitgeist, but you'll only notice three at this point:

1. We've dramatically improved the site's page load speed by batch-generating pages on a nightly basis. Much faster than building the pages on the fly...
2. We've begun to edit participant-nominated book topics for consistency. Aside from some basic word-smithing, we're normalizing topics. The result should be a much clearer and better picture of what books you—the UX community—would like to see published.
3. Throughout the site, you'll notice that we've swapped our alpha label for a beta; pretty cute.

But the most exciting change is currently invisible. We're finishing up work on an account administration interface. This will allow us to abandon using Survey Monkey to gather your responses, and make content entry and editing far easier and more efficient for everyone involved. This step should dramatically expanding participation in UX Zeitgeist, making it a truly communal tool.

As always, we'll keep you posted...
