Media was always already social. If I email my friend a link to a YouTube video, is the Internet a social network? I think what we think of when we think of 'social media' or a 'social network' is an integrated platform that lubricates particular potentials, like being able to create and share content with friends and fans. But there are other ways to realise those potentials, including ones that require the interfacing of different platforms (or media, in the McLuhanian sense), or what might be perceived as different platforms at one scale, and the same platform at another scale, as per my Internet example. And, the multiplicity of platforms, and the interfacing between them, might confer additional advantages and open up yet more potentials.
What's wrong with the Arctic Code Vault [1]? Is the only problem that they didn't seek your consent? How is it different to deploying a new availability zone and having your public repos accessible on another server? Your code is preserved verbatim, and it's not possible for GitHub to provide their service without the right to make verbatim copies of your code, which presumably you agreed to as part of their ToS.
I'm glad that Copilot is bringing the grey areas of copyright into discussion. If I write a book and it is copyright, what's the smallest unit which is covered by that copyright? Each word is obviously not. Some sentences will be fairly generic and I will not be the first person to write them. But some sentences will be characteristic of the work or my own style. Clearly how we apply copyright to subdivisions of an original work is an open question.
Yes, I was also quite excited until I saw the message limits, it feels very archaic.
So far the best email service I've found is Tutanota, who provide a custom domain for €12 / mo if you pay yearly [1], which is the cheapest I've found so far. I also like how my mail is encrypted at rest. The only downside is I have to use their web client which has limited features.
I much prefer Zulip's thread model to Slack's (it it bolt-on and poorly done: threads have no titles, they get lost in history as there is no way to list threads, and they are optional so people only use them some times), but I prefer Slack's UI to Zulip: in Zulip everything feels a bit 'tight' and too close together. Also the big outline box for keyboard navigation is distracting to me.
Seems like an interesting study in developer-driven design: in Zulip the mental model is much better, but the appearance of the UI isn't as nice.
