Defense of what? Of not making superficial criticisms or praises about individuals based on the number of miles traveled and/or number of countries visited.

It's possible that a blog/blog entry is garbage, but that isn't a product of the number of miles traveled and/or of countries visited.

There is plenty of garbage coming out of people who have traveled way more than 150k miles and been to more than 15 countries. For example, there is a carpet-bagger occupant of a known address in the nation's capital who epitomizes that kind of person and loves attention by going on the attack or who knows what else. Would I find him to be a producer of good miles/points material in social media forums? No. But his famous social media rants grab plenty of attention.

So which miles/points blog is it that is famous for social media garbage produced by someone whose travel history is neither all that rich nor all that poor? Checking out garbage can have its purpose at times too, but spending too much time on garbage is a waste of time IMHO.
