I sort of had a did.txt for 3 years, updated quite often during my working hours (at least once a day, if I were super busy, to dump all my daily activities and notes). It was quite useful for standup meetings and such. It is a pretty gigantic did.txt now, and in 3 years can you guess how many times I needed the info sitting there? Zero... go figure :-(
Totally, i've never actually fully read my did file (just started), but I find the act of writing a concise summary of what I've done to be the major benefit.
