I first wrote about "Internet voice" on qassia; click the title above and you can view what we call intel.
Okay, a brief synopsis; your Internet voice (blogs, networking postings, etc) tells a lot about your character and how well you work with others.
If you can't speak kindly to others in your Internet voice are you going to make it in the business world?
One of those people that see your post, or advertisement, etc is either going to be a customer or refer YOU to someone else.
Work had at smiling when you type and be spiritually affectionate to those you don't know and can't see. Why? Your income counts on it.
