This reminds me paper I had written couple of years back on performance based filtering.
Couple of weeks back a friend and me were discussing about product / service reviews in various sites and blogs. Are they not commercially motivated?
Another incident came to my mind is when I was working a lab level for a product support. My products used to run on IIS web server and it wasn't working fine a specific customer case. Customer googled and got some suggestions to change IIS configuration. IIS administrator just went and made the changes suggested by the site. It didn't solve the problem and look it didn't created also a new problem. Me and my mentor had discussion about it during the time about people blindly trusting the blogs and web.
How to trust a website or content in a website? How do I know that it is not commercially not motivated? The article is opening a lot of questions!!
Any way the news papers content I don't trust any more. Read this artile about TOI
