One of the areas that make blogs really unique and revolutionary is that plagiarism is actually encouraged. It is not necessary that a company creates all its blog material from scratch. Doing your research and collecting useful data from other sources is highly encouraged.
One point of etiquette is to make sure you reference and link back to your source. If you do this, it is flattering to the original author and a source of pride for many bloggers. This is another change from the tradition business mindset of what’s mine is mine.
A good business person today is one who is seen as a body of knowledge who can help many people. We live in a world where solution selling is King and whoever has the most solutions to offer sits atop the throne. So in the world of blogs, don’t be shy to share what you have learned. Pass along the wisdom of other and you just may get yourself a seat in the palace.
