Its a problem that is the scourge of the computer world. For an area named "Information Technology" it seems the seductive obsession of analysing Technology utterly predominates, and analysing the important part, "Information", is completely ignored throughout industry and education (save a couple of islands, such as Warwick University where Darwen teaches). I worry about the lack of resources to address this, especially with sites such as debunk being defunct.

As an eternal optimist however, I await the day of Proposition Oriented Programming and somone manages to fix the /correct/ side of the 'impedence mismatch'. (I've just coined the phrase POP by the way. Its a winner I tell you). Received on Mon Jan 22 2007 - 18:12:44 CET
