Ruby Weekly Issue 55
August 18, 2011
From the Editor's Desk..
Welcome to issue 55 of Ruby Weekly! This week I'm experimenting with including images with some items. Sorry if it seems a little random to start off with but I want to see how it goes. On Ruby Inside, images have helped a lot over the years and I want to see how it plays out with e-mail too.
