I really liked the appearance and flow of this StAIR resource. I think it is laid out clearly, attractively and is easy to use. I also like the narration audio, as I think the narration grabs the learners attention. It fits many UDL principles by incorporating interesting visuals, audio and learning resources. I found it instructional, as I have often wondered what the major differences were between the various web browsers. At no point did I feel confused about what to do. The links all worked well and I found the format to be clean and professional.
