In the brand-spanking-new category of "you learn something new every day" goes:
1. SVG. Fine. I give up. I now understand the coolness that is SVG. And I grok that I get to play with it at work.
"What do you do at work?"
"I kinda do a little of everything. This afternoon, I worked on visualizing 'Romeo and Juliet' with SVG."
2. iPhoto can happily store Photoshop files. Hooray. I can edit my photos, save them, and then export them directly to JPEGs. Makes things mucho easier.
