Want to know when I post new content to my blog? It's a simple as registering for free to an RSS aggregator (Feedly, NewsBlur, Inoreader, …) and adding www.underachievementunlocked.com to your feeds (or www.garoo.net if you want to subscribe to all my topics). We don't need newsletters, and we don't need Twitter; RSS still exists.
