I spend a non-trivial amount of time keeping up with the latest and greatest in web development. In particular, I often find myself on websites where somebody is discussing Web2.0, social networking, etc. - and I often make comments. Many of these folks are downright hostile about me adding my viewpoint to the discussion, especially if it doesn't match their own viewpoint. (And don't dare write anything negative about Google.)  

Which made me look a bit closer. And most of these so-called web-2.0 'experts' are writing about the latest web technologies on a blogger or wordpress single-user weblog; otherwise known as a soapbox. Their formidable experience in social technology is limited to obtaining a facebook or myspace account. Few if any of them have ever actually written code.

So as always, when evaluating the opinions of experts, consider the source and determine the level of real expertise. There are a lot of so-called experts out there these days. Installing a WP blog and obtaining a MySpace account are not in themselves qualifications about anything more than an ability to install a software package and register for free accounts.

[As for my own qualifications, I don't claim to be an expert at anything.]
