Bathtub Thoughts

In scientific literature there's generally two ways to cite someone:

• If you're writing a technical paper about something related to technology, you typically cite the paper in square brackets.[The Art of Citation; Johnson et al.; doi: 10.4208/jcm.1512-m2015-0242]
• If you're writing in sociology, you typically cite the author in round brackets. (Clarke 2013)

Nevermind the square/round brackets, my point is that in technology-related fields, typically the name of the paper is considered more important than the author. A paper can have many authors, and not always all are listed. Meanwhile in sociology, the author is considered more important than the name of the paper.

This reflects the main difference between Mastodon and Lemmy:

• Lemmy is content-centric, where you have communities (focused on a topic) as the central element of organization, and they can have posts.
• Mastodon is people-centric, where you have person/user as the central element of organization, and they can have posts.

This is why lemmy mostly appeals to people working in IT and tech, and that's why there's mostly nerds here.

Just to put things into proportion:

This is vienna. Vienna has an area of around 400 km².

And the blue area is the area that would have to be covered by solar panels to produce enough energy for the whole city:

Source: I did the maths myself. I assumed that per person around 30 MWh of energy/year are needed. Data for this: our world in data, energy usage per person. It's well known that 1 m² of solar panel produces around 200 Wp and that's 200 kWh/year. So you need about 150 m² of solar cells per person. Vienna has about a million inhabitants, so that makes 150 km² of solar panels approximately.
