"You okay?"

"Yeah, it's just a lot to take in."

"A century's a long time."

"Yeah."

"If you click on any of the blue phrases or words they'll take you to an article about that thing."

Lucien clicks on the advances in science and technology link after two tries and reads that for a while.

"And the first one I found you is just the twentieth century, it's the twenty-first now."

"Is there an article for that too?"

"Of course!"

There were a lot of other articles to click on in the first one....

"I might want to spend a rather lot of time reading this encyclopedia to help me catch up with events,"

"Wikipedia is great. You can't believe everything you read on it, since it's user-editable - you can try it yourself if you find a typo - but it's much more accurate than you'd expect given that."

"How does it stay accurate then?"

"Small army of dedicated volunteers keeping track of recent changes more significant than typos."

"Is it encyclopedia-sized?"

"Oh, bigger, much bigger."

...

"How big?"

He checks his phone. "Seven point four million articles."

"Wow."

"That's really good."

"Wikipedia is awesome."

"How many people help write it?" 

"That I don't know off the top of my head - I mean, there's people who write entire articles and then there's people who correct typos, either number would be misleading in its own way."

"I suppose that makes sense - have you ever edited it?"

"Sure. On the typos level, mostly, but once I got so annoyed with something on a page about a dungeon that I wrote up my take on my blog so I could cite it as a source. They don't let you post original research directly to Wikipedia."

"Your blog?"

"It's like a newspaper column that I publish all by itself, online."
