> to sell only a few thousand copies
Good joke! To sell 100 with current Nim community size may be possible, maybe 200 with a chinese translation. A free book may have indeed 1k readers. My guess is that manning sold some hundreds of NimInActions indeed, but that was when Nim was new and had some hype, in 2015. And they sold them for only 20$. Now many people know already Nim, so they may not want to buy a book. And we have a lot of free resources now.
