You know, like in limenviolet, they had a sock[/stashbusting]marathon. (Well, they did a sock marathon.) Maybe we could do something like that... What they did was posted pics of their stash before they started stashbusting, and over the period of time (I think it was 3 months?) was they posted what they made an how many yards of yarn used converted to miles. (First one to knit 5 miles apparently won something, but...)
Just a thought.
