Let's face it. Reading reddit every day kills productivity as it is easy to develop a dependence on browsing reddit to compensate for an otherwise (apparently) dull moment. Yet, reddit provides some informative links. I often enjoy reading the submissions and comments posted in the programming subreddit.
This site helps you to establish a habit to read reddit once a week only.
How? Simply add the following feed to your feed reader and never visit reddit except through the weekly feed updates.
r/programming [rss - weekly]
To subscribe to other sub reddits, in the above URL simply change
/rss/yoursubreddit. To subscribe to the main reddit, use this link.
How it works: the RSS feed is updated every week with the links from the "top" page for "this week" (example). Effectively this only includes highest-voted links submitted in the last 7 days.
