Use hyphens to separate words in domains (LOW PRIORITY)

When you're putting keywords
in your domain and URLs, you
should consider separating them
with hyphens (-) rather than
mashing them all together or
using underscores (_). Search
engine spiders can't tell where a
word ends and begins without
cues like hyphens, and most
computers recognize hyphens as
the end of a word, but see
underscores as part of the
word.
