I love getting to know other jewelry shop owners on here.
I follow them on twitter, and retweet/reply to their posts that interest me.
Or I will message them on here via etsy if I find a shop I completely adore, I will let them know that and what I love about their shop and items.
This is a great way to get to know others with the same interest and get the conversation started.
Facebook is another way, an easier way I feel than twitter to communicate with others who share a passion in the same hobby.
I also have a blog, and I pride myself on always replying to comments that are left and actually reading them. This lets my readers know that I am real and I do see their comments! :)
