(A note on Daily Deals: All prices current at the time of posting and subject to change. Most items marked Daily Deals are good for only the day posted.
Many large promotions have discount pricing that is set by the publisher. This usually means that titles can be found at a discount price across most platforms (with iTunes sometimes being the exception). If you have a favorite retailer you like to patronize, check the title on that website. There is a good chance that they will be matching the sale price.)
Daily Links are interesting links I discover as I go about my online day. The frequency and number of links posted depend upon the daily news. I also post other, different links of interest on Twitter, Facebook, and on the Google Plus eBook Evangelist Page.
