But I also just finished up developing Safari and Chrome extensions to extend nvALT’s notational velocity (or something ;) into the browser. 

Page One extension for Safari and Chrome fixes them, automatically displaying the single-page version of articles for several popular news sites. Install the extension now:

Post to Twitter is a Safari 5+ extension for Mac users. This extension, with Twitter for Mac, makes your Twitter experience on the Mac, I think, a whole lot better.

NoMoreiTunes is an extension for Safari 5 that stops iTunes Web Preview pages and other links to the iTunes store from automatically launching iTunes on your Mac

Automatically restore your previous browsing session

Chromium Updater.app consists of just a small shell script wrapped in an Automator application. It doesn't make Chromium auto-update itself, but it sure makes the process a lot easier. Just quit Chromium if it's currently running, double-click Chromium Updater.app, and then resume doing whatever you were doing before opening it. Chromium Updater will let you know when it has finished updating Chromium.app.
