What is the economic term for a good whose demand increases with price because people assume that higher price is correlated with higher quality?

You are probably looking for the term luxury good, some of which are examples of a Veblen Good. There's a problem though, the term luxury good refers to goods that are not considered essential. The economic term for goods whose demand rises with a positive increase in price, are in fact called Veblen goods.

I get confused over this as well, you just need to keep in mind that the term luxury good refers to the income elasticity[1] of a good and Veblen good refers to the price elasticity[2] of a good.

Some luxury products have been claimed to be examples of Veblen goods, with a positive price elasticity of demand: for example, making a perfume more expensive can increase its perceived value as a luxury good to such an extent that sales can go up, rather than down.
Although the technical term luxury good is independent of the goods' quality, they are generally considered to be goods at the highest end of the market in terms of quality and price. Classic luxury goods includehaute couture clothing, accessories, and luggage. Many markets have a luxury segment including, for example, automobile, wine, bottled water, tea, watches, jewelry, high fidelity, and chocolate.
Luxuries may be services. The hiring of full-time or live-in domestic servants is a luxury reflecting disparities of income. Some financial services, especially in some brokerage houses, can be considered luxury services by default because persons in lower-income brackets generally do not use them.[3]

[1] [math] \frac{\Delta Q_d / Q_d}{\Delta I_d / I_d} [/math], the change of a good's demand w.r.t a 1% change in income.

[2] [math] \frac{\Delta Q_d / Q_d}{\Delta P_d / p_d} [/math], the change in demand w.r.t. a 1% change in price.

Is aggressive and careless black hat SEO on behalf of an enemy a viable (albeit possibly illegal) strategy for getting them blacklisted from Google?

I respectfully disagree with my colleague Rand. In fact, I am surprised that someone whose business is promoting sound optimization practices and who advocates the position that white hat SEO is the only way to go would stop at enforcement.

Both of the most recent Black Hat SEO cases that came to light did so because a competitor was more aware than the search engine. This brought to light the inability of the search engines to adequately enforce the rules that they have created. So, if a business is in a dogfight and their competitor is not playing by the same rules, the choices are: 1) enforce the rules equally with the help of the search engine or 2) everyone gets to do what they want , how they want and there are no rules.

How harmful is eating frozen food once a day?

Frozen food isn't inherently unhealthy; some brands make frozen meals that are very nutritious, and even organic if that's your thing.

Worry less about the frozen/non-frozen distinction and more about the actual ingredients. One frozen meal a day is only bad for you if it contains bad stuff.

What websites focus on connecting hyperlocal communities for people to sell each other handmade goods?

I work for a hyperlocal marketplace (Zaarly), so I’ve given this some thought. Here are my personal (and probably biased) ideas. There may be other options, but this is the option that I’m best informed to speak on, so I’ll do that…

This is something that Zaarly is addressing, in a way. Zaarly’s focus is to help people with skills and talents make money doing what they love. In many cases, this results in people teaching skills, or practicing something like photography or dance. Some sellers do more practical work like cleaning, construction, or fixing cars.

But in many cases, the result of people putting their talents to work are custom goods, which Zaarly does support. We have a number of sellers that do things just like that: custom woodwork, furniture, jewelry, knitting, sewing, and more.
Zaarly is most definitely Hyperlocal, as each city is it’s own marketplace, so you only see people who are in your area. We provide support for marketing, copywriting, and photography to our hand-picked sellers to give them the best chance of succeeding.

Here are some examples of my favorite Zaarly Storefronts based on custom goods:

Myriah started her own clothing line of beautiful custom dresses for little girls, and does all of the work herself: https://www.zaarly.com/myriah/cu…

Yasmine in NYC is an absolute master of the men’s suit: https://www.zaarly.com/yasmine

Ian & Yuko team up to create custom bow ties in San Francisco: https://www.zaarly.com/smithbran…

Molly makes children’s dreams reality with personally-made picture books: https://www.zaarly.com/molly

Demetrius (in Milwaukee) is an insanely talented college student who loves customizing sneakers: https://www.zaarly.com/groundbre…

For the lady readers, Simone handmakes bikinis, underwear, bodybutter, and scents: https://www.zaarly.com/cocomama

Mackenzie crafts some incredible jewelry that’s beautiful and unique: https://www.zaarly.com/kenzkouture

Chrissy creates incredibly unique jewelry through the process of Watercasting: https://www.zaarly.com/christine…

Jay is a master surfer who will build a custom board for any rider from scratch, the old-fashioned way: https://www.zaarly.com/equinoxsu…

In fact, we have a whole category of “Custom Creations” on Zaarly, so head to your nearest city, and browse through what’s available!

If you’re interested in becoming one of our sellers, you can apply here: zaarly.com/selling — if you have any questions, tweet/fb/email me!

Why did Twitter drop the nudge feature?

Probably because it would have ended up being annoying like so many Facebook pokes and whatnot.  Plus, do you want users participating just because they've been prodded or because they genuinely like the service?  Don't know for sure – just speculating.

What is the backstory to Haystack (the anti-censorship app for Iran)?

This is a great summary of what happened
http://www.oblomovka.com/wp/2010…

One of the  many new facts about Haystack that the large team of external investigators, led by Jacob Appelbaum and Evgeny Morozov,  have learned in the past few days is that there were more users of  Haystack software than Haystack’s creators knew. Despite the lack of a  “public” executable for examination, versions of the Haystack binary were  being passed around, just like “unofficial” copies of Windows (or  videos of Iranian political violence) get passed around. Copying: it’s  how the Internet works.

I think that this paragraph says it all.
