I just followed all three of you.
http://twitter.com/#!/Bohemian_IceI'm not totally up with all Twitter does, but like everyone here has noticed, you get lots of views from tweeting your new listings. I have also included my sales, treasuries, and older listings in my tweets and it really seems to bring more views. One thing that I have recently learned to do is to use "hash tags." This gets your tweets on more lists and ultimately to more viewers. There seems to be a lot of things involved with hash tags, but the simple way to explain it is...
in each tweet, you add key words with a # hash mark before it...
example:
Garnet wire wrapped bracelet
http://www.whatever #etsy #jewelry #gemstone #teamxyz
these hash tags, put this tweet on the etsy list, the jewelry list, the gemstone list, the teamxyz list...after you tweet it, if you click on the hash tag, it will bring you to that list. This makes it easier for people looking for a particular item.
I googled "hash tags" to learn about them, so you should be able to find more info about them if you like. Hope this helps :)
