I had this comment from someone (who I'll allow to remain anonymous) on this
news post:

"You post more non-meteorite related crap than the next ten people"

So I thought I'd comment just a little more on the article, as I replied to said
person:

"There has been debate on the list about the terrestrial ages of weathered NWA
(meaning-- from the Sahara) meteorites. How long meteorites take before
weathering away is related to exposure to water. Evidence of the Sahara being
verdant less than 5,000 years ago puts a constraint on the estimates of Saharan
meteorites being tens of thousands of years old."

"Other news posts I make are related to solar system and planetary formation,
which are directly relevant to meteorite formation, and about meteorite parent
bodies, such as the moon and Mars. If you actually care about the science of
meteorites, then those things should interest you."

(latter suggestion trimmed)
