Ancestry.com's DNA offering had two components two it. The really cool part was where it matched you against other people who submitted tests _and their tree_ (if they had one, and it wasn't private). So you can truly confirm your work, which is keen. The rate of identified fourth cousins (genetic match AND confirmatory tree on both sides) rises by the week.
The much less important part of the offering is an ethnicity calculation. (Please, feel free to complain about the whole idea of an ethnicity, much less a genetic calculation thereof. I will probably agree with even those arguments I haven't already encountered.) Ancestry's ethnicity breakdown has been unusually bad, if you can imagine scaling bad-mediocre-good on something as f'ed up as an ethnicity calculation. I know (see above paragraph) who I am descended from and related to, and the old analysis didn't match. Like, at all.
The 2.0, match, however, is excellent. So that's something. Especially if you have big gaps in your tree, this might be helpful to you?
That's it for the genealogy part of this post. The rest is an unrelated remark about some Amazon news.
As near as I can tell, this describes Amazon and Procter & Gamble partnering so Amazon can drop ship you paper towels and similar household paper goods.
The Brad Stone book (which I have on the kindle, but haven't read yet) has been chewed over pretty thoroughly, including the Quidsi/diapers.com acquisition. In the comments thread over on The Digital Reader, I noted that one of the vanishingly few things I didn't buy on Amazon was diapers (either cloth or paper), and didn't really have an explanation why (their prices are competitive and I have Prime -- I did the whole time the kids needed diapers, which was for a very long time). I also don't buy paper towel, toilet paper, pads or similar through Amazon, and I don't have a really good explanation for _that_ either (altho maybe I do; R. tends to buy that stuff in large lots at Costco).
While I don't think (haven't really checked the other articles on the topic) the coverage has gotten into inventory smoothing, that might be a factor encouraging P&G and similar companies to pursue this partnership, especially if it gets them hooked up to the Amazon subscription model. This kind of household paper product is notorious for having completely pointless variability in ordering at the retail level, which causes problems for the producer; direct from the maker's warehouse to the customer should reduce that problem.
I feel like I should follow this up with a post about two unrelated news articles involving companies which start with the letter 'B'. But I won't.
