If you're a twitter user that is online interacting and exchanging ideas, thoughts and laughs I think you're ready for the next step. And that is, to start adding links (URLs) to your tweets. Sometimes there's more to say or share than what the 140 characters allow. Now, if you're a veteran twitter user you know that it's not a tool to just go on and plug yourself or business every time you tweet. It's about interacting, discussing, and helping others by adding valuable content to the stream. Many social media gurus say a good ratio is 8 to 1.
