I don't normally defense sports casters, but "hone in on" just sounds more edumicated. And I think the point might be "getting closer and closer to the target". You "hone in" on your target by mentally sharpening your aim. First you look at that part of the field; then at that particular player; then his hands. Plus, can you "home in" on third base? That could be mighty confusing for some ball players.

But to hone in on the question, please remember we're talking about sports casters and Dubya Bush. Seriously, what do you expect?

I don't think I'm a registered user, but my name appears in red.
I just discovered this website today; perhaps the rules have changed?
I appreciate your passion for language. However, I suggest you never visit Louisianna, where you'll hear such phrases as, "I use ta could!"
English is most definately a living language.

Ophelia, with "etc.", why would you put a period after "et"? "Et", as you say, isn't an abbreviation.

As to your original question, I find it a bit disheartening that you find a no-dot "eg" in an English Studies document. Of course, if New South Wales is in Texas, then I can understand....
