Why are Todo Lists (a.k.a. personal productivity systems) so hard to build well?

I’m genuinely curious. I was listening to the last episode of Cortex, and one of the hosts (CGP Grey) brought up a similar point regarding personal productivity platforms. OmniFocus, the reigning champion of the industry for professionals looking for a deeply customized system, has been staggering in their ability to ship the next version of their application. Much of the market consists of various different packagings of the same offering. Grey’s thesis of these platforms essentially boils down to this:

window-based co-occurance is a matrix whereby we increment the value where each row is the center word, and each column is the number of occurrences of that other word next to a window of that word.

This approach is fine (not great), but if your vocabulary is HUGE, your word vectors will be exactly that length—bad. Therefore, we take this matrix and we SVD it; then, we chop off the smaller singular values to create a low dimensional approximation of our matrix.
