The Secret Garden

So I'm currently reading The Secret Garden to Rio. In the first scene, the protagonist is rescued from her house by the army after having slept through a cholera epidemic that killed everyone she knows:

"I fell asleep when everyone had the cholera and I have only just wakened up. Why does nobody come?"

"It is the child no one ever saw!" exclaimed the man, turning to his companions. "She has actually been forgotten!"

"Why was I forgotten?" Mary said, stamping her foot. "Why does nobody come?"

The young man whose name was Barney looked at her very sadly. Mary even thought she saw him wink his eyes as if to wink tears away.

"Poor little kid!" he said. "There is nobody left to come."

At this, Rio mumbled, "Everybody's dead, Dave. Dave, everybody's dead."

A thing I don't understand about Project Wonderful

I have three sites currently running Project Wonderful ads. One of them is Joule; another is shavian.org.uk.

Joule has a "skyscraper"-size (160x600) sidebar on every chart page. It gets about 800 hits a day.
shavian.org.uk has a "button"-size (117x30) image at the top left. It gets about 50 hits a day.

Consistently, the shavian.org.uk ads have been selling for 20¢/day and the Joule ads for around 1¢/day.

I don't get why people are willing to pay twenty times as much for the shavian.org.uk ads. In fact, of course, the bids are mostly placed by bots which are given a certain sum of money and told to go and spend it, but that doesn't decrease the mystery.

If I had a lot of spare time I would try running control experiments. Is it the fact that the lack of available space makes people want it more (i.e. in general people are more likely to bid higher for buttons than skyscrapers?) That seems strange. Is it that shavian.org.uk is a site under "books and writing", whereas Joule is about "blogging tools"? Is it just coincidence? I don't know, but I'd like to.

Answers to crossword clues

2A. Part of it's a turning body (6)

SATURN, guessed by many people. This is a very traditional sort of clue. "Part of" indicates a substring search. "itSATURNing" contains the substring. "Body" is the surface clue: Saturn is a heavenly body.

The other two don't follow the traditional surface/deep model:

3A. What the town of Titipu was to the Mikado (8)

SUBTITLE, guessed by a few people. The operetta's full name is "The Mikado; or, The Town of Titipu". I like this because it leads people up the garden path: they spend hours trying to figure out the proper term for a city ruled by an emperor, and how to fit it in eight letters.

1A. Get rid of the stuff legally (4, 4)

TAKE SILK. Nobody got this. It's a pun on "stuff", which also means the substance that entry-level gowns are made from. Lawyers in the UK (and some other Commonwealth countries) wear stuff gowns until they reach the exalted heights of Queen's Counsel, when (in the same way that PhDs do) they exchange their stuff gown for a silk one. This is known as "taking silk". Again, garden path: you are supposed to think of some contraband substance which you must "get rid of legally", but that's not what it means at all.
