It depends. For a lot of content on HN, I simply save to Pinboard with a tag. Most of that never gets read, but when I happen to need to work on something that uses, say, a graph database, I’ll review my “database” tag bookmarks to see if there’s anything useful there.

If I actually intend to read the content of the link and not just potentially return to it later if needed, I’ll save to Instapaper, which is configured to automatically create a Kindle-formatted digest of all the links and send it directly to my Kindle on Friday mornings. It’s like a mini-magazine of only articles I care about.

Some other commenters have suggested other “Send to Kindle” options, but I prefer this because those create a single Kindle item per article, while Instapaper’s digests compile a whole weeks worth (or more, the length of time is configurable) of content into a single Kindle “book”.
