Here’s something you might not have considered — Reddit. It calls itself a “platform for internet communities where your votes shape what the world is talking about.” There are a range of topics on Reddit, some not for the faint of heart. But you can find some science sub-Reddits. Here’s the general science one to get you started. It has close to 6 million subscribers. That’s a lot of power.
You also might be interested in the AMAs (Ask Me Anything) in the right column. They’re Q&As with scientists.
It’s just for fun, but be warned, it can be a deep rabbit hole once you start.
