Nick Carr has been pondering some contradictory data…

Some hard data is coming out this week on the adoption of Web 2.0 tools by companies. Yesterday, Forrester released some results from a December 2006 survey of 119 CIOs at mid-size and larger companies. It indicated that Web 2.0 is being broadly and rapidly brought into enterprises. Fully 89% of the CIOs said they had adopted at least one of six prominent Web 2.0 tools – blogs, wikis, podcasts, RSS, social networking, and content tagging – and a remarkable 35% said they were already using all six of the tools. Although Forrester didn’t break out adoption rates by tool, it did say that CIOs saw relatively high business value in RSS, wikis, and tagging and relatively low value in social networking and blogging.

Tomorrow, McKinsey will release the results of a broader survey of Web 2.0 adoption, and the results are quite different. In January 2007, McKinsey surveyed some 2,800 executives – not just CIOs – from around the world. It found strong interest in many Web 2.0 technologies but much less widespread adoption. McKinsey also looked at six tools. While it didn’t include tagging, it did include mashups; the other five were the same. It found that social networking was actually the most popular tool, with 19% of companies having invested in it, followed by podcasts (17%), blogs (16%), RSS (14%), wikis (13%), and mashups (4%). When you add in companies planning to invest in the tools, the percentages are as follows: social networking (37%), RSS (35%), podcasts (35%), wikis (33%), blogs (32%), and mashups (21%).
