Etsy has gotten very big, very fast. This year, sales are at about $800 million.
"Their growth on all the major metrics you want to look at has accelerated really consistently," says journalist Rob Walker.
Walker recently wrote a story for Wired Magazine with the headline, "Can Etsy Go Pro Without Losing Its Soul?" Here's why: Etsy makes money from its sellers: 20 cents every time they list an item and 3.5 percent of every sale. Today, there are some 800,000 sellers.
