With Google Reader closing its doors in July (which stinks because I use it multiple times per day), now is a good time to make a switch.
For those who want to stick with RSS, you can grab the feed here. Note the change in feed URL. I used to use a service called Feedburner to deliver the RSS, but that's owned by Google, too, so it's probably best to move away from there.
Then of course you can follow @flowingdata on Twitter.
Or via daily or weekly email.
