You raising earthworms? Or just interested in them?

Raising. I have a bin with some, and just trying to collect more info. :)

Zappos CEO Tony Hsieh once tried to build a worm farm as a business:

I did a presentation on Zappos last semester, and I think I mentioned the worm farm!

That's awesome. He remembers that worm farm fondly.
