After some research, I've come up with these three fun facts:

Did you know that the word "Steem" was created first before its analogy to the word "steam" was realized?

In deriving the name for a new currency, @ned and his team listed some names that signified influence, one of which is "steem". From this long list, they chose the word "steem" for the impression that it makes, similar to saying "steamed authors". Later did they find out that "steem" relates to "steam" on its purpose of fueling economy and how it is reflected in making power (steam engines produce power). They also found out that the reason why they were able to make "steamed authors" as basis is because the word "steam trains" actually influenced a lot of English idioms i.e.:

• This conversation is picking up steam.
• This conversation is getting off track.

Did you know that @dan, @ned, and their team of developers started little, working on a basement?

Yes, the huge Steemit community today started with a group of dreamers working on a place shown at 3:02 of the reference below. That is the basement of blocktrade.

On his keynote speech at SteemFest, @ned said that when they initiated in developing the Steemit blockchain, they had no capital. Luckily, they knew @dan and Donna from Blocktrade who offered them a place. @ned reminisced about the basement jokingly telling the listeners that it was hand-dug. After 4 months of developing the Steemit blockchain, they finally found an office.

Reference for answers 1 and 2

Did you know that @ned, the CEO of Steemit has the same name with a Hollywood photogapher?

Yes, he has! :) haha. Anyone can easily search it on google, or click here, though that Hollywood photographer is already dead. XD Nonetheless, it's still fun to know.
