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.
I used to have trouble remembering the exact Markdown syntax for links. It's easier to remember when viewed in light of Markdown's intent of being as close as possible to normal human-readable text:
Edit -- other pitfalls:
There must be no space between the close square bracket and the open parenthesis.
If the link contains a close parenthesis it must be preceded with a backslash. So if a link's last few characters are
foo)
the Markdown version's last few characters should befoo\))
(note the two close parentheses -- a backslash-escaped one that is part of this particular link, followed by one that is part of the Markdown link syntax).In Less Wrong's Markdown implementation, the link needs to include the
or
part at the beginning. If it's left out, the link text and everything will disappear.
