Ok, well here's the talking points as to why it stopped.
Op-Ed Columnist - Joe Nocera's Blog - NYTimes.com
They couldn't keep up with the censoring, supposed "payback" (the blog just stops short of calling them "threats"), and the posting of her address.
Well, first off, if they were actually inclined to allow all people to post opinions, then they wouldn't feel "overwhelmed." But since they felt it necessary to keep everything one-sided, of course the majority overwhelmed them.
Secondly, what does taking down insults and vituperation do? Does that magically change the people's minds who wrote them? And if that's truly what they were (we'll never know, since we didn't get to see them), then why not leave them up, as it only takes away from their credibility?
Finally, I really don't know what the purpose of someone putting her address out there was. Maybe a liken to how owners are treated in certain states who release their information? Or maybe it was because many people wondered what state she lived in that she claimed to have gotten so quickly, easily, and with no background check. Regardless, anyone with internet access (and this is blog, so you have to have that to see her article in the first place), can find that information in about 30s.
Frankly, my original theory (before I saw the above reference), and I still believe it has some merit... is that she jumped the shark in the first blog. She pretty much wrote all she could. By limiting her exposure with this "I'm going to do the minimum" rule, she couldn't take this any farther. No going to the range to practice. No personal interaction with pro-carry people. The only thing to be written was 3 more blogs of the same paranoid drivel. And she even justified her original conclusion right in the first article, so you could believe there was no hope she would modify it in the least or even come up with some profound new conclusions (whether they supported her original position or not). I really wondered if the blog would possibly last the full 4 weeks with such little content to go on, and it didn't even get to week #2. In this case, I say... good.
