After working with Instructables.com for 5 years I've determined that the vast majority of projects posted and featured on the site a complete junk with respect to the technology category. The site has mostly been overrun with authors that are promoting PCB manufacturers, or authors that are publishing articles of junk science (aka free crystal energy). The editors can't distinguish the difference between good science and bad. I've worked with the community leader and he admits that editorial oversight isn't what it used to be but doesn't offer any solutions. Instructables.com is basically dead as far as I'm concerned. Review the articles at my site www.netzener.net and compare them to any of the technology articles on Instructables.com and you will see what I mean. Over 90% of the articles published on Instructables are basically "look what I made" vanity posts that do not include enough information for anyone to replicate the work. And even when they do, it's obvious the author has not a single clue how the project they present actually works. Instructables is crap, and they know it.
