Yes, blogs are great! When I started on Etsy a year ago, I had several friends in the same boat, just beginning, asking me "How do you do this and that to build an Etsy shop?"
So instead of emailing each and every thing I was learning to multiple people, I started a blog about it - specifically what it takes to set up and work a shop on Etsy.
It's been fun. It's a different approach than blogging about my artwork, but has really helped me connect with other Etsy sellers and learn from/with them! As I learn stuff, I share. I do promote my own paintings (a bit) but mostly Imy blog promotes the work of other Etsy sellers (via illustrations on my blog posts).
I'm at myetsyblog.com/
I use a simple WordPress with a unique domain name - really easy to learn and do.
If any of you want to be featured in my blog, just convo me.
