I am very excited about my newest twitter connection Holly Hanna and her website "The Work at Home Woman." You can follow her tweets @Holly_Hanna. http://www.theworkathomewoman.com/
The website offers loads of useful information for women who are starting their own business or who already own a business. She has some wonderful articles and guest bloggers on the site that provide a ton of resources.
If you have a business, be sure to list your business for free on the site under the tab "Woman Owned." Make sure you stop by this website and learn some new tricks of the trade!
