I'm interested, except I recently bought his _Introduction to Linear Algebra_ (to go with his opencourseware). I'll probably eavesdrop and do the exercises in that one instead.

Yeah, that's the argument in favor of the other Strang: it's more standard and would allow piggy-backing on the open course. Still, the material is mostly going to overlap.

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.

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. [ 1 0 0 ] [ 0 1 0 ] [ 0 0 1 ] OK, worth a shot.

It may be good to hide solutions behind a pastebin link, rather than directly including them in a comment & spoiling things.

Interested; please include me. Once the book arrives I'll have to confirm I can make the time.

In terms of how: I was part of a terrific, useful "HN reads SICP" group a while back (http://news.ycombinator.com/item?id=428248, couple of us made it through to the end). In that case the meeting place was simple (irc) and we generally linked to our answers on pastebin/github/personal site which supported whichever features we needed it to. An HN thread per "meeting" could work similarly as a hub.

It is probably useful for each person to chime in separately, e.g. "I agree that this is the right answer" or "I also have this confusion", despite this not being ordinary HN etiquette. That allows us to know how many people are participating and evaluating answers, which is difficult, especially given hidden comment points.

I agree. I'm superstitious about origins. When something spontaneously happens at location X it's good to let it continue to evolve there. I say we stay where the party started. We can post occasionally and nobody who's uninterested need look at it. I also confess to tasting sweet irony in the idea of turning HN to more productive use. I feel like I've finally got my enemy in a corner. (The internet has never stopped…

I'm in. Got the 3rd ed. while waiting for the shipment of the 4th (possibly long wait). Let me know if you're in a similar situation.
