Hey there! I’ve torn myself away from exploring Google Wave to talk about the episodes of TechStuff we published this week. I’ll be sure to post my thoughts about Google Wave in an upcoming blog post. We may even tackle it as a podcast subject in the near future, so keep your ears open.

In Monday’s episode, Chris and I talk about the different kinds of image files you’re likely to encounter in our digital world. What do those file extensions mean? What’s the difference between a JPEG and a GIF? Does anyone use the BMP file format? Why are some viewable in Web browsers while others aren’t? When should you use a particular file format? Chris really did the heavy lifting in this episode, educating yours truly about the different file types and why they are important.

Facebook, applications and your privacy became the focus of our discussion on Wednesday’s episode. The social network gathers new users every day, many of whom appear to install each and every app that crosses their paths. Is it a good idea to load up on applications? What about all those quizzes? Are they harmless fun, or could you be sharing your personal information in ways you didn’t intend? Can an app developer get a look at your information even if you have your profile set to private? Chris and I talk about the risks of installing applications and how you could even expose your friends to unwanted attention.

We continue to receive great feedback and podcast suggestions from our listeners. Please keep those suggestions coming — we want to cover the topics you’re interested in. For those of you waiting patiently for an episode on technology conspiracies, we’re working on it. The topic is huge and we want to do a great job. Got another topic you’re dying to hear more about? Let us know!
