Building a Blockchain, or, what I learned about blockchains by building one. https://halfanhour.blogspot.ca/2018/03/building-blockchain.html
(It's worth noting that this is an example the learning method I advocate.)
Why is it always the case that the point in the article where the author wrote "The above should be straight-forward" is the point where you have to stop and think "what just happened here?" https://hackernoon.com/learn-blockchains-by-building-one-117428612f46
(I think this is what Google was trying to do with 'circles' https://support.google.com/plus/answer/6320407?co=GENIE.Platform%3DDesktop&hl=en but it was way too complex and user-hostile).
Mastodon I use for conversations. Like this one.
I keep my Mastodon connections to just a few in number and delete people if they drown out everyone else.
This creates a nice informal community for me based on nothing in particular except that I like the people in it and find them interesting.
If I wanted to replicate this with a different group I'd need a different environment (or another copy of the same environment). Each group would be different.
I use different media for different purposes, & once in a while something great emerges from that, but I don't think you can force it or recreate it, you just have to be open to it (even that an be hard).
Twitter I use for announcements & public messages. I look things up on Twitter but I don't follow.
Facebook I don't use.
Google+ I use for longer posts (but too short for blog post) especially with links.
LinkedIn I use for professional connections but almost co communication at all.
At the 1983 Canadian University Press conference in North Bay a group of us had created a great conversation group, sharing the space with an open door between our rooms. But on New Year's eve the hotel burned down (electrical fire) and we relocated. We still had the same grouping and the same shared space, but the conversational dynamic had been broken, and it was never the same. #smallstories
Sunday night I was looking at my code and thinking it was loading too slowly. So I moved everything over to my website. Loaded fast - but I really broke it in the process. I'm still fixing it, two days later, because I had forgotten to save the original fully-functional template. D'oh. #smallstories
I once had a teacher tell the class that Lake Huron is larger than Lake Superior. Being a geography nerd, I was quick to correct her. The next day I came in with proof in the form of the World Almanac (which I would read every day). She then told me that I had actually said that Lake Huron was the larger of the lakes, and that *she* had said Lake Superior was the largest. My first experience of gaslighting. #smallstories
