Sonja and I recently recorded our first Screenr screencast titled Anatomy of a Google SERP (Search Engine Results Page). Screenr allows you to easily create screencasts for Twitter. Once you record a screencast, you can tweet the link, publish to YouTube, or download the .flv.
We recently launched a website for our pals at myPlatinumSound.com — a Jacksonville recording studio. Built with Joomla! CMS, this site offers an online booking request module, PayPal payments, and Twitter feed.
