I'm really pleased Tim, "The Man With No URI", has started blogging, and already has pushed out some great posts. I will try and answer some of the points raised by the topical Onwards Delegation Problem, but was diverted by Tim's aside:

B-oo-kk-ee-p-e-r incidentally, is the only word in the English language I'm aware of with three double letters in a row. I'd love to be shown others...

Unix boxes ship with a words file, which on my Mac has 234,936 entries, and a quick grep:

egrep '(.)\1(.)\2(.)\3' /usr/share/dict/words

revealed:

bookkeeper
bookkeeping
subbookkeeper

Scraping Wiktionary:

for i in a b c d e f g h i j k l m n o p q r s t u v w x y z
do
    curl http://en.wiktionary.org/wiki/Index:English/$i
done |
    grep '<li><a href="/wiki/' |
    sed 's/^.*title=\(.\)\(.*\)\1.*$/\2/' > words

gave 72,018 words, with no plurals, but still only revealed "bookkeeper".

There are a bunch of open word lists around the Web, many harvested from Gutenberg, but Moby Words, having 619,361 words and claiming to be "the largest word list in the world", could only come up with:

assistant bookkeeper
bookkeep
bookkeeper
bookkeeper's
bookkeepers
bookkeeping
bookkeepings
bookkeeps
double-entry bookkeeping
single-entry bookkeeping
subbookkeeper

Oh well, I did at least try.
