today I have, for various reasons, been thinking about information ecologies

[kaberett]

Almost entirely courtesy of recessional, at least this framing of it. I do not have anything insightful or original to add, but perhaps I can interest you in:

On information ecosystems as a concept: have overviews from wikipedia and Information Matters (which I have not vetted further); and another on JSTOR, which I haven't actually even skimmed in its entirety because it's definitely bedtime. Broadly:

A practical approach to low-pressure but widespread countering of disinformation.

Assessing information sources, complete with demonstration: tumblr discusses SIFT (plus origin).

And, of particular relevance to me this evening, the value of consistently removing wretched stickers, and optionally replacing them with something constructive.
