I'd never heard of this site selected by our our roving editor Rhiannon but
I'm really glad I've now discovered it. As Rhiannon says "This is a site that
makes curious people happy. It started out as an effort to find, curate and
index all the great videos on the internet, and now provides more than
170,000 how-to videos & articles from more than 17,000 specialized creators,
spanning 35 vertical categories and 424 sub-categories."
