This has been my favorite class on Coursera so far (I've taken 5), and what's weird is I wasn't even going to take it at first. It was offered before Coursera had millions of classes, and to me it just sounded like it "meh. might be interesting." If that's you, I think it really well go far beyond expectations. The one-on-one interviews with industry professionals that Dr. Chuck has access to really give an added layer to the history. I think one of the biggest strengths though, really, is that he's just a good lecturer. A lot of professors, maybe not even any fault of their own, just aren't that interesting to listen to. Dr. Chuck makes things very understandable without it seeming dumbed down, and has a sense of humor to boot. I mean before this course I knew a router had something to do with the Internet, but now I really get how routing works. Not just that, but I have completely rekindled a childhood passion for technology. I think it's just contagious.
One of the biggest points I want to make is this course does not take a lot of weekly time (as in hours to commit). I think it takes about 3 hours a week to watch all the videos. I think this is great because as awesome of an initiative as Coursera is, some of us just lead really busy lives. The time commitment to this course is as much or as little as you want it to be. Some weeks, I would watch/read the "supplementary material" just because I was so into it, but other weeks where I didn't have time, I just rushed through the videos and finished the quiz. Totally doable for anyone.
Tip: If you ever want to contact Dr. Chuck about a bug or anything else about the class, tweet him @drchuck!
