[BR-Crater] where people are finding the crater web page

[Ian Kluft]

Web browsers sometimes provide a "referrer" field to say which web page
they're following a link from.  There's no referrer when you type in a
URL.  And some browsers just don't report it.  But it still gives you
a sample of where readers are coming from.

In the past week, the most common referrer was the listing on SciScoop.com
with over 60 reported referrals since Tuesday.  That's running near the
same rate as the Rocketry Forum posting the previous week, as I expected.

Some people found it via search engines.  Here are search terms that brought
them there this past week.  Some were looking for it.  Some weren't but
clicked on it anyway.  The ones without quotes around them probably got
*a lot* more results than just this one since those can get any page with
all those words anywhere on the page.  Search engines used were mostly
Google, some Yahoo, and a few others.  Misspellings are quoted verbatim.
