I have repetitive stress injury, and need to investigate a new mouse and keyboard that can help with my condition. I went to Google, searched on ergonomic keyboards and received a number of hits - websites, mostly corporate or trade journals with reviews (paid for? promotions?) - extremely limited and not very helpful. So, I decide to search on blogs - and my first hit is a real Hit - Amy Hengst who maintains a blog devoted to home treatment for RSI . And lo and behold she has a comprehensive, informative list (and up to date) on ergonomic keyboards.
So here is my opinion drawn from this search experience. Websites are primarily corporate, designed to deliver a message leading to a sale, and often dated. The weblog - personal ones - can be corporate and sales driven but then there are also gems like Amy's where the message is up to date and more important than the sale. She as a blogger wants to share information and experience, not generate a sale. So for this trust test I side with the weblog.
