Q: Okay, so how does this work?

Don’t leave tabs open all the time. If it’s an article to read, send it to Instapaper. If it’s a resource you can make use of, bookmark it in your browser or on a site like Pinboard. If it’s something you want to download, a tutorial you want to complete, or it’s otherwise action-oriented, put it in a to do list.

Q: But don’t you lose track of some websites or never get around to reading some articles after filing them away?

Yes!
