Lifehacker.com is a great site. However, you must be careful. It contains scripts from 3 well-known ad-servers that implement tracking cookies: quantserve.com, scorecardresearch.com, and doubleclick.net.
If read-later services aren't your thing, your browser's bookmark bar can be a convenient place to stash articles and posts you plan to getting around to. You can do what Lifehacker reader leftymcrighty does, though, for better placement: reduce your permanent bookmarks (email, search sites, banking, etc.)
They share information or provide links to sites that can be "NSFW" (not safe for work).
They usually post it in thread title but most kids surf by images, not text.
