Yes, me too, when I look back to my oldest guides (some of them are not even public anymore), I see how things were evolving from then and how I was looking for answers. It's like a history book for Bitcoin evolution.
Is nice to write guides and see how you evolve yourself, educating others in the same time.
yes, and the opportunity to ask and learn from the devs - the first tier of builders! It's so cool that many people still have no idea what's going on, yet you have a tiny few people figuring out how to build on top of Bitcoin, wow.
