From the website http://www.coolsciencefacts.com/
cool_science features Drew Olbrich's "weekly dollop of scientific perspective" which is always informative and often amusing.
flickr_365days is a syndication of the RSS feed for the Flickr tag "365days" in which participants take a photo of themselves every day for a year. It's a great way to explore creative photography from amateurs to pros, but the volume is a bit rambunctious. I would recommend this feed if you need a lot of browsing entertainment on a daily basis. Otherwise, it may be overwhelming.
From the website http://www.zefrank.com/theshow/archives/2007/01/012607.html comes "The Show" with Zefrank which is a weekday video blog which began March 17, 2006 and will supposedly end March 17, 2007. Still, it's quite informative and entertaining and I'm stunned there are only (at this moment) 44 LJers currently subscribed.
