When I was issued my Dell laptop for my new high school tech teacher position, the first thing I noticed (moving from a Mac) was the lack of media content creating/editing software. “Well, I’ll just have to work this year to collect a group of web-based programs that will do the job,” I resolved. Luckily, the folks at Mashable have done it for me. In fact, they have put together the most comprehensive annotated list of sites I have seen to date. Take a second and check it out. I’m convinced even the most knowledgeable media editor would find something new on this list.
