Count me in. I already have Strang's textbook and have watched some of his lectures.

However, I was quite impressed with a few minutes of Khan Academy I watched the other day. I don't know what the dependency chain is for their L.A. modules but that site seems to have some good metadata and group organization tools.

I've been liking Khan's linear algebra stuff too, but feel like its time to level up.

I'm in. How do we coordinate? http://convore.com perhaps?

I seriously think we could just do it on HN threads... There are feature-y-er places to do it, but this place actually works.

I think old threads get locked (can't post new comments) relatively quickly on HN which would make it tough, it would involve making new posts and expecting everyone to find the new one. (Feel free to correct me on the locking thing)

So do we post our answers and get downvoted if wrong? (and sometimes anyway)

It's hard to beat an elegant site like this that we're already registered for, but I'm having trouble visualizing matrices in this markup.

OK, worth a shot.

Once in a blue moon I go back and find hanging replies to my comments, so I'm pretty sure these things stay alive for weeks, which is as long as we'd need them to.

Chapter ever two weeks plus exercises sounds simple, doable, reasonable. Let's do it that way. Once we feel like we've picked our book, let's decide on a date to start; 2 weeks from that date, one of us will just post a "STUDY HN:" post for the first chapter. We can figure out the formalities, like, what do those threads look like, once we get started. :)

Convore wouldn't be a bad idea for coordination and meeting. How about it ?

Which textbook are we talking about? Timing isn't perfect for me, but I'm willing to at least try until everything catches up with me.

Already mentioned, but if you really like using a textbook I can't recommend Strang's book enough. Its awesome, and go really well with his lectures.
