The main thing I don't understand is what incentive does anyone have to keep me plugged in after I passed away?
I could answer this, but this question can be easily answered by yourself by thinking a little more and doing some googling and reading of cryonics literature - your question is obvious and so, since cryonics advocates are not known for their stupidity or for simply ignoring obvious problems, you should expect them to have at least tried to answer it.

I don't understand the downvotes on this. It looks like an appropriate answer to a confused newbie question to me. The financial and moral incentives for not pulling the plug are all well represented in the cryonics literature.
So, apparently appsumo is having a custom reddit bundle, a bundle meant to appeal to redditors, and 10% of the proceeds get donated. On the surface, doesn't sound _that_ interesting, except...
Take a closer look: http://appsumo.com/reddit-special-deal/ and find that the recipient of the donations will be... SENS!
I find this to be an interesting development. It wasn't the "custom transhumanist bundle" or "the custom sens bundle" but "the custom reddit bundle". Yes, "reddit" doesn't, in and of itself, count as extremely mainstream as such, but I'd say it's still an interesting development.
