Twitter for Small Business - Download the PDF Guide
If you're a small business just getting the hang of this Twitter thing I suggest you check out the Twitter for Business resource centre. This pdf best practice guide highlights plenty of good examples, tactics and ideas to help you tweet more effectively
It's packed full of good tips and different types of posts that will help you meet, connect and engage more people interested in your products, services or topics of conversation.
I really liked this graphic too, suggesting a few ideas of how, where to promote your Twitter handle. Not quite sure about seeing @justinflitter on my shoes though!
