They can also be indicative of an author who slept 2 hours before getting up at 1am to spend hours over spreadsheets and powerpoint presentations so to make up for the fact that the shit is hitting the fan on the same day that he has to spend most of it out of the office in meetings, and started commenting on HN as a short break away from working :) And now it's time to head into the office for a couple of hours! p.s. Fun fact, the "two" was a genuine mistake. When I don't pay attention my hands often type ridiculous phonetic errors, such as their/there. Heh, even as I wrote this I had "time" instead of "type".
