"Where can you find Flickr and Apple in the same room? At the AJAX Summit of course. An insider report from the press-free zone where the future of webdev is being mapped out." by Jonathan Boutelle for SiliconValleyWatcher
"The O'Reilly/Adaptive Path AJAX Summit, held Monday and Tuesday in San Francisco, was a "geeks only" affair."
Jonathan offers insights and lots of links to Ajax demo's and developers.
Tiger Woods & Why BI Tools are Awful, by Paul Kedrosky from Infectious Greed. "Recent readers of this site may not realize that last year I wrote an OpEd for the Wall Street Journal on the trouble with Tiger Woods: I argued he swings too hard."
You gotta check this out. Yes, it is ajax related. Yes, Paul has a demo in Flash of Tiger Woods swing, but considers ajax and offers caution on jumping in too fast.
Did I mention Tiger Woods? Just did it - your take. You gotta go vote now.
...and I came across this link Feedtagger on Steve Rubel's site. "...allows you to "tag" your feeds under different headings." Nothing really new, but check it out. That is a pretty a common feature in most advamced cms and blogging apps.
