You can tell someone is passionate about what they do when they feel that the terms used to describe their job, comes into question. A thread at WebmasterWorld named Link Building is a bad phrase, started by WebmasterWorld moderator Receptional, goes into a discussion about the word "building" versus "development." It even goes deeper into using the word "reputation" versus "linking."
The thing is, the thread only has three posts. Are "link builders" satisfied with the term "link building?" Or would they prefer the job be termed, "reputation development?"
That does depend on how one performs the task. Is it a robotic fashion? Is it a more detailed and meaningful to you? What I mean by that can be explained by people who think at this level. People who research, who build the reputation, possibly before the ground is settled for there to be reputation built. I'll stop there and keep it short.
