What's a nub?!
Simply put, a nub it's the 100th part of a boon. You get these smaller units by getting your tracks played back or by getting your grafix being seeing and downloaded by users. Accumulating nubs gets you boons and it's easier to gain nubs since they're smaller 'units'
eg. an entry on a ohc gives you 30 nubs (rather than boons) In practice, you can easily get many nubs to get up to 100 boons in a little over a month and a half (let's say 17 OHBs and a remix compo) so ohbing enough accumulates enough nubs to get you boons
