Last year, in a piece for The Age, I wrote about what appeared to be a change at the Lego company as to how they received user innovations.
That article talked about the Lego Factory concept that had users design new lego sets for a share of the royalties. This was a good example of user-based innovation as described by MIT's Eric von Hippel in his book Democratizing Innovation.
It turns out that that was just the tip of the iceberg according to February's Wired. User-based innovation has appeared to have infiltrated the whole innovation process at Lego.
