Ask HN: What do you use to save and read articles and content?

I've recently found myself repeatedly in the position of wishing to save articles, documents, and free books I find online for later reading, but a lack of a central repository makes the prospect of returning to them difficult.

I've considered several options:

- Some tool that extracts content and puts a document into a single format eg. PDF, Markdown, ePub - "Save for later" tools in web browsers / OSs - Evernote or similar - A folder that is synced with dropbox, Drive, etc...

Essentially my goal is to save content, mainly text but also images and possibly video content, to a central place in the cloud that I can access it later in a clean, unobtrusive manner (without ads, source formatting, etc.) for later reading or reference.

I'd be interested to hear what approaches other people use.
