So what does the online world look from the vantage point of an RSS fanatic? Mostly, quite spare and minimalist. Not all feeds bring images through with the text, and a lot of embeds don't work either. If these seem important, I click through to see the original, but that doesn't happen very often. My reader just sorts all entries chronologically, so I see a random jumble of everything as I scroll backwards. To give you an idea of what a mixture it is, here are the subjects of the five articles at the top of my feeds right now: shark hunting in India, praise kink, 1970s architecture, AI's influence on filmmaking, and the growth of the anti-system voter in the US. I suppose I could sort the feeds into subject matter folders, but I find the constant variety makes all the information easier to parse. I think it helps me do a better job of sifting out the good stuff, too.
