The Instructables that sounds a little bit like the indestructables and reminds me of some of the cartoons my kids like such as the Fantastic Four or the family of superheros I can never remember the name of. Anyway as the names more suggests its about instructions on how to do things, its an offbeat idea but a little along the lines of wikihow etc.
I like it actually and have started posting on it also see my instructable post here. This will be interesting to see how it performs, but I do like the look and feel of the site so I am sure to be back for a few more attempts at least.
We’ll see how things work out, but sites with a niche like this and memorable name tend to do well in my experience at least.
