Odd? LJ habit. Why?

So, I understand why you would want to link ( <lj-user=foo>) to a user if you were discussing something related to them, but why do folks feel it's necessary to do it every time they say someone else's name in the course of a post? I might even be able to understand it if you did it the 1st time, but then why every time thereafter in the same post?

So..many of you do it. Why?
