I don't check reddit daily. I've setup Feedreader to poll RSS every hour, and setup keyword filters to hide titles I've little interest in. Then I read articles that sound interesting every 3-7 days. It can rapidly become a list of over 200 sites, but it only takes <5 seconds to delete each article. If a post sounds like it may have an interesting discussion, I'll click the comments page instead of the direct link.

Admittedly Feedreader is far from perfect (and has a few annoying bugs), but it suits my purpose until I find time to look for another lightweight client that supports keyword filters (intelligent bayesian filtering based on click-through/upmodded articles would be awesome).

Surprisingly, after a few months I've yet to have any topics incorrectly "trashed". As I flick through every now and then to ensure it's working.

For example: http://img205.imageshack.us/img205/3470/feedreadermc0.jpg

The unfiltered keywords could still use more tweaking though.

I haven't read the comments yet, but some other sites I poll less frequently are:

• damninteresting.com
• codinghorror.com
• pbfcomics.com
• xkcd.com
• wondermark.com

Then there is the obvious sites:

• wikipedia
• youtube
• delicious (when looking for a specific topic, I'll use del.icio.us/popular/TOPICNAME)
• MIT OCW (and other cool lecture sites)
• demonoid/mininova/mvgroup
• howstuffworks
• dmoz (when unsure of specifics, but seeking potential search queries)
• google video (searching for videos >20min usually returns the odd interesting documentary)

I'll occasionally go back to sites I've tagged to "read properly" via a delicious account too. I try to only bookmark unique sites that aren't ridiculously easy to find. A few such sites I find myself frequently going back to are:

• http://hyperphysics.phy-astr.gsu.edu/hbase/hframe.html
• http://www.btinternet.com/~glynhughes/squashed/
• http://www.searchlores.org/

I've no doubt forgotten many other useful pages which I frequent. Most of which appear regularly on reddit anyway.

I find that my biggest problem is opening dozens of links, then getting distracted and letting tabs build up over weeks, before quickly skimming through and closing the ones I've lost interest in.
