The author mentions the fine Hacker Monthly but curated e-mails also have a role to play here. If you want something with more coverage and volume but still remain sane, http://www.hackernewsletter.com/ is a weekly newsletter with the best of HN's links by HN's own 'duck'.
I do similar work with my Ruby Weekly, JavaScript Weekly, HTML5 Weekly and StatusCode newsletters and frequently get e-mails from people who say they like being subscribed so they can turn down the 'noise' they get on Twitter, etc.
There are thousands of such regular, curated digests in almost any medium you could think of. Not just e-mails or magazines, but podcasts, link blogs, YouTube channels, and Twitter accounts too. Have a good look around on the topics that interest you, subscribe to the digests, and then skip the noise.
