HtDP appears to be eight years old, and SICP is 25 years old. Therefore, the number of people who have been exposed to the one is likely to be several times larger than the number exposed to the other. That may explain why one seems to be recommended much more often than the other. That certainly applies to me: I read SICP about ten years ago after MIT-educated bloggers recommended it [1], but I was on vacation from the field when HtDP was published and this is the first I've heard of it. Thanks for the recommendation! Perhaps someday I will manage to read it and will then be in a position to recommend it in the future. ---- [1] Though they weren't called bloggers at the time.
