@tiotasram interesting ideation topic.
Not sure if I have time to respond today, but just wanted to note that this aligns with the general interest and focus of Social experiences (SX) at https://coding.social which I elaborate on as a hobby, and perhaps one day my job.
The disadvantage of microblogging is how ephemeral it is, but the advantage is reach. Should you be interested you are welcome to share results on the social coding forum, which serves as a note-taking tool: https://discuss.coding.social
