As you know I am fairly new to the world of blogging and twitter and various other social media options that I am yet to discover. I really enjoy the world that has opened up to oscar and ruby through these mediums and honestly believe time on twitter is time well spent. Not just for helping to grow as a business, but for making friendships and genuine connections with vendors all over the world.
If you have the inclination there is a wealth of info out there on how to use twitter well.
To save you the trouble (if you are interested!) I've linked for you here a great article by chris brogan.
It's worth the time.
