I sometimes describe Instapaper as "/dev/null for web content". I reflexively share to Instapaper not to read it later, but to absolve guilt for not reading it at all. It is one of my weirdest web habits, on reflection.

OTOH, back when del.icio.us was good, I used it for roughly the same purpose.

These days, I still send links to Instapaper when they are essays or articles. I send links to Raindrop.io when they are anything else, basically anything the Instapaper text extractor would fail on. Things like repos, interactive charts/graphs, photographs, videos, etc.

I still think it is behaving roughly as /dev/null. I do sometimes think that, at least nowadays, you can ask an LLM to visit your bookmarked links and do some semantic search over them. But I guess the best use case is just saving it for later/never rather than wasting time on it now.
