One of my biggest goals is to start promoting my writing. There are a lot of good resources out there that I have used in the past that haven't cost me a penny.
Twitter is always a good resource and I've been using it more and more recently to promote and share my writing.
Even if you're not a writer, there are other ways to use resources like Twitter to tweet about your business.
Some even use tweets to write great how-tos for personal and business use, such as, "How to Set Up a Funded Proposal to Advertise Your Business -http://t.co/8Nl3Mi0tQl"
For me it's as simple as tweeting a link to this blog post.
