It’s been a busy week at HowStuffWorks.com. On top of the normal schedule of podcasting, live shows, blog posts and articles, we’ve also experienced the joy of upgrading the software on our computers. Immediately following that came the traditional 45-minute where-the-heck-did-they-put-copy-and-paste ritual. Then there was a building-wide fire drill that disrupted us for an hour or so. Oh, and there’s the guest appearances.

On Tuesday, Randall Bennett invited me on TechVi to discuss the new line of Apple products that hit stores this week. Yesterday, Chris and I sat down for a phone interview with Chuck from Galactic Watercooler. We talked about Carl Sagan, Cosmos, the Voyager program and science fiction. The episode should be up later this weekend — definitely check it out. They run a fun show and have had some really interesting guests on in the past.

On top of all that, we also published two new episodes of TechStuff! You remember TechStuff — it’s the show with electrolytes (it’s what plants crave). This week, our shows focused on two related topics: touch-screen technology and the Zune personal media player.
