Time-travel barter goods, a short list.

Coming from the 21st Century

Peanut butter cups

Chocolate + sugar + peanut butter. A winning combination throughout the ages. Even people who can't understand your language can immediately determine the value of a peanut butter cup. It's Prime Directive friendly (difficult to reproduce and unlikely to affect the course of other recipes), consumable (fewer twonky problems), cheap enough (for the traveler) to give to a child for a quick bit of information, and valuable enough (to the local) to barter for items of immense value.

350-Farad capacitors

(idea from @wikkit on Twitter) A 350-Farad capacitor is small enough to fit in the hand and available for $11. An electrical engineer from the mid-1800s to mid 20th C would easily be able to verify it and would value it highly.

I'm taking 2018 off Twitter

TLDR: I'm stepping away from Twitter for 2018, from January through December.

I've talked before about how [Twitter is a communication service][2], not an entertainment channel. I resisted changes to the format, retreated to third-party clients, and relied on lists* to make sure I'm seeing what I want to see, not what Twitter wants to show.

None of that is why I'm taking a break, though. Twitter's been good to me for over a decade. I met some of [my favorite people][1] there. SpaceUp owes its existence to Twitter. (Specifically to @cariann, but that's another story.) I work at a rocket factory because of Twitter. (Thanks to @malderi, yet another story.) I still hold that if Twitter were to go away, we'd have to invent something to take its place. (Something with a bit more empowerment and a lot less abuse. I can dream.)

I've actually spent more time on Twitter this year than before. I commute on buses a few hours a day, and Twitter is a reliab
