Defining best practices for Web 2.0 is a huge challenge – the whole point of Web 2.0 is that it’s continuously evolving. But hats off to John Musser for trying. His report is a grand, readable sweep across everything Web 2.0. Well, almost everything – OPML is an omission.

There is sufficient detail here to give both Web 2.0 virgins and troupers a good grasp of the essentials of the subject. It covers the opportunities, threats, issues, technologies and cultural changes driving the adoption of Web 2.0.

Web 2.0 refers to a web that is no longer a one-way, or limited two-way, affair. Multiple participants engaging with each other in unpredictable ways have triggered a storm of innovation and social media reaching to, and across, the organisational firewall.

Enterprise 2.0 also gets a look-in in the form of recommendations scattered through the report. Although Musser says he planned it this way, they read like a series of afterthoughts.

The report provides useful checklists and links. It lacks an index but, at 100 pages, it’s not difficult to find your way around. At $300+, it is nobody’s casual read, but it’s reasonable value for anyone trying to get a hold on this multi-faceted and fast-moving field.
