Tim O’Reilly’s talk at eTech this March just got posted on ITConversations. Called “Watching the Alpha-Geeks,” (link is to more info and download) it’s a great 30 minute overview of the trends underlying the bleeding edge of new tech. Very cool, very listenable. A great way to catch up or brush up on some of the most exciting things going on in the space. The world really is changing and this talk does a great job of explaining the upsides and some reasons to be concerned. O’Reilly is fantastic, as are many of the speakers in the ITConversations podcast series.

If you’re in the mood for podcasts, the most recent edition of the Gillmor Gang is not to be missed if you’re interested in new media vs. old and the changing advertising landscape. Amanda Cogden from RocketBoom, Jeff Jarvis from BuzzMachine/About.com/NYTimes and Richard Edelman, head of the PR firm that represents Walmart and is smart enough to employ Steve Rubel, are all the guests. And it’s only 30 minutes long! So if you are put off by the usual hour length of one of the best podcasts online – this could be your big chance to check it out. Very forward-looking stuff in this one.
