Heaven's to Etsy!

Now that I am a craft person, I have to come to realize that it's all about Etsy. If you thought the Ottawa Christmas Craft Sale was a zoo, check out all the crap on the Etsy. Yes, I am into the whole alternative marketplace thing, but....Holy Shit! Is it just a way for people to fund their craft obsessions? Clearly, I need some Etsy-savvy person to explain all of this me. Help! Please give me some analysis.
