I've added Irving Wladawsky-Berger's blog to my "blogs I read" list.
Irving (Bio, Meet the Experts) is IBM's Vice President of Technical Strategy and Innovation, which makes him one of the company's most senior spokespeople on its technical direction. As he says in About me, "I am responsible for identifying emerging technologies and marketplace developments that are critical to the future of the IT industry, and then organizing activities in and outside IBM in order to capitalize on them." He was a big part of getting the whole "e-business on-demand" thing started. So it's cool to hear what he's thinking about.
I've just discovered that Irving and I are thinking about some of the same things. (Which is really no coincidence. He helps originate ideas that IBM starts disseminating and then I eventually pick up on). For example, we've both been blogging about values (him, me). Some other interesting posts: The Economic and Social Foundations of Collaborative Innovation, The "Outside-In" Enterprise, and On Demand Three Years Later - A Personal Reflection which includes "What is an On Demand business and why should I become one?"
As you can see, Irving talks more about business issues whereas I usually talk about how WAS works (so you can see why he's a vice president and I'm not). All the same, I think these sorts of business issues are important and should be of interest to a J2EE- and WAS-oriented audience like you. So, check it out.
Bill picked up on Irving's blog as soon as it started. Now that I see some of his discussion tying into some of mine, I think you'd be interested, so I've added to my "blogs I read" list. BTW, you can see the list in the right column of my blog page.
