reference-to-twitter vs. twitter

I'm starting to think that we don't need the reference-to keywords for brand names, i.e. Twitter. We have the keywords, reference-to-twitter and twitter. Maybe they should all be twitter.

At least one other contributor agrees with me, because I've noticed that someone is switching these keywords out. Maybe the staff could help this person by having the system automatically switch the keyword to twitter whenever someone tries to submit reference-to-twitter.

It will be easier for him to switch them all out if no new examples of reference-to-twitter are coming in.
