Only identifyable info has been stripped, I still have # of times each document has been dl'ed, just not exactly when and by whom. The zipped DjVu file has been downloaded about five times daily the last year, and it comprises about 4-5% of my used bandwidth... In comparison, my archive.zip (all *.html and *.txt files zipped) is downloaded on average ~40 times daily, comprising 20-25% of my bandwidth (I updated it today, by the way, it is now 24 MB, containing 47 MB of texts & pictures).
