In some languages like Japanese, personal pronouns tend to carry strong connotations and are often avoided in favor of names and titles, in both formal and informal contexts.
In others like Finnish, pronouns and conjugations indicating person predominate, and it would generally be considered odd if not rude to refer to somebody by their own name during a conversation. (Sorry, Dale Carnegie!)
Is there a term in linguistics for this phenomenon, and if yes, are there any standard measures for where a given language falls on the spectrum?
Update: Thanks all! There's a new shiny Pronoun avoidance page on Wikipedia now, please edit away.
