What else? Well, here are three of my personal exhortations.
First, just to recapitulate, I think we need to look back at our own field for ideas that could influence current developments. Bush, Nelson, and Engelbart have gotten well-deserved attention over the years, but there are other long-lasting and significant projects in our field. To pick just one example, I'd recommend ZOG/KMS - many of their earlier ideas including their provocative UI perspectives are quite relevant today.[15]
Second, I recommend doing more of what we've long shown a talent for - looking to other fields for inspiration. Here, I will plug the cross-fertilization that is happening with digital library work.
Finally, I want to exhort you toward a somewhat different kind of integration involving community building.
