After checking out Twitter, I think it's an amazing tool to promote yourself as an artist by following and interacting with the right people online. You don't feel like you're barging in on their work and lives since you only have 140 characters to spend to communicate with them.
I will be tweetsteringing my artwork updates, as well as a bunch of other crap like Star Wars toy photos and stuff.
Feel free to follow me at @Hishgraphics and say hi.
