Check out this artilce at instructables.com about making a solar fan.
Incidentally, I just bought 2 solar fans for 2 of my friends for $14.99 a pop plus a hefty $7 something for shipping. The package is still in the mail but this raise the interest of the relevance of the instructables’ usefullness and its articles and community’s growth.
I have known about instructables a while ago as it’s another web2.0 company, and you have to read about some web2.0 companies at some points in time (I regularly follow UnderTheRadar.com and SiliconeBeat.com blogs.) The idea of instructables.com is such a good one that everyone knows that someone’s gonna do it. There are lots of people out that with interesting ideas and pet projects that they are willing to share, and there are even more people who’ll be curious to keep on reading what’s on.
Even though Wikipedia provides a way of free knowledge contributions, one thing for sure is instructables.com handles users’ input much better than wikipedia.com as there is a higher level of community-driven factor. Moreover, instructables.com has better support for graphics and images to make the artible more visually attractive and clear (the on-photo-comments is a great feature to have) as a picture worths a thousand words. Comments are generally welcome, making the community interaction even better.
I’d say instructables.com’s success in terms of scaling up and a stronger community driven by the noble purpose of knowledge sharing is guaranteed, it’s just a matter of time and words of mouth.
