I'm also naturally curious about the byte count --- using the accepted standard of 5 for words to characters, and since I almost never post anything but ASCII, I've been writing approximately 1.25KB per day here; or just over 5.5MB worth of text so far. Considering that English text compresses very well, and using ~20% as a rough ratio, this means that all ~1.2M words of my comments here, compressed, would still fit on one 3.5" floppy disk.
