One of the things that has been incredibly helpful not only in promoting my blog and helpful for finding new things to blog about has been Twitter. Do you have a twitter account for your podcast?
New to Twitter? Check out this video from Common Craft here. A really nice simple overview of Twitter.
The Craft blog had a great post before Christmas - "Crafting Your Online Presence: Twitter Tools" - while this post is written with a crafty audience in mind, I think the info here is still very useful to podcasters too. Diane Gilleland, who produces CraftyPod - a blog and podcast about making things, has put together a great list of tools to help you do more with Twitter.
My favorite from her list is HootSuite and I am excited to check out Twitalyzer.
What are your favorite Twitter tools? And just a reminder - you can follow Libsyn on Twitter too - http://twitter.com/libsyn
