Is ETSY really worth it? Or not?

Good morning all...I have a question and would LOVE some feedback please.

WHAT makes an (or your) Etsy site successful?? ...in Sales that is.

I have been a member for quite a while now, and I have had a whopping 2 Sales!!! Thank you buyers!
I have dropped my prices, placed giveaways on my Blog...saturated the network with links to my site...and yet so few Sales.
I'm not sure whether to hang in there or not.

A new blogger friend from my home country posted a very similar question...please take a peek at Mariann's Blog and Shop.She is an amazing talent with such beautiful illustrations.

Have we come on the Etsy scene too late?
Please,please,please...a few Etsy tips would be hugely appreciated!!!

Until later...today...
