I discovered this series earlier in the year via HN. I don't remember which entry I started with, but I read it, then a couple more, then went back to the beginning and read everything in order. I read them all over a period of days. I found the series utterly compelling and kept checking back every week for a while in hope of updates. I'm happy to see that there are new entries now and I'll be reading them this weekend.
I can't comment on the current direction since I'm not caught up yet, but I wanted to thank you for writing what you have. I knew maybe a third of what you had written about before reading your series, and your writing and thematic organization are great. Your writing is clear, full of colorful details without becoming too digressive, and unifies the entries with an effective thematic arc that I haven't seen before. It's better than any published-in-book-form popular history of technology that I have read in the past decade.
