A union with fewer that 6k members worldwide and an extreme ideology seems like an insane place to start actually, unless your goal is to turn people off unions.
The IWW's ideology is hardly extreme considering the prevailing ideology in the US. And the IWW is small, but their track record speaks for itself.
What track record do they have in, lets be generous and say the last 50 years?
That seems like a ton noise with very little, if anything to show for it. It still seems like the IWW is a weird place to start a search for unionization, or a model to follow.
I don't know what "noise" means in this context, especially as interpreted though the lens of Wikipedia where you are certainly reading through editor biases.
You said the IWW has - as in the present day - "an extreme ideology". Where is your evidence?
What track record do ANY unions have in the last 50 years?
