Speakers of 19th century English?

Well, what I had in mind was a flyby of an object of a roughly comparable size, and I'm pretty sure that ~0.5-1km sized objects have been mapped pretty exhaustively. So, yeah, there will be a lot of flybys before 2027, but the flybys of things we don't know about yet are bound to be somewhat less significant.
The interesting thing here is the somewhat skewed shape of the size distribution of known NEAs, which suggests to me that the skew due to detectability happens somewhere below the ~300m region. That's what makes me think that most of the ~1km sized stuff has been already discovered.
the problem that i've found is that it's not like literacy where you pick a language and you learn the syntax.
Sorry to burst your bubble, but that's not much of a literacy either.
Yet reading and writing, basic literacy, help billions of people who are neither authors, nor poets in doing their everyday job. Literacy enabled a huge revolution in the workforce, and life in general.
That's what I understand to be the aim of the HtDP project - to put a decent number of people into some reasonable place between the alphabet and Shakespeare.
