Usually I stick to whatever the original poster may have decided to add, which is usually nothing. Since most images aren't posted with a view towards being viewed on the web, and since they usually come plastered with promotional comments by whatever program generated them, I convert them into progressive format, stomping on any comments in the process. But sometimes, very occasionally, there'll be a comment that was actually put there, by a person. The last time it happened was almost a year ago, but once a year is enough to remind me that there are others out there who don't view image comments as just a way of keeping your name before the public. After reading over a book on VHDL and experimenting for a few days I was familiar enough with it to start working with it, but when I started reading my Japanese text one evening several months ago, as one might read any ordinary book, I came to a halt about seven chapters in with the distinct impression that my brain was about to boil right out of my head.
Some books are more information-dense than others, it seems.
Up until now, I'd thought technical manuals were near the top of the scale, but it looks like language lessons are whole order of density above that. Well, there is a pill, but it's awfully big, and it takes a long time to swallow. The blisters from the bicycle tire incident are mostly healed now, and my thumbs are peeling like mad. I haven't gotten a spare inner tube or any tire levers yet, but it occurrs to me now to fill in some of the events of that day that I left out. After discovering that I'd ruined a brand new inner tube, I was very annoyed indeed.
