Honestly, I use search engines very little anymore.
SEO games make them almost useless to me. Certain well curated Reddit feeds, and sources where it looks like people give a toss is my preference. IRC, Slack, Discord communities are real time with a person, and probably “better” for discovery.
Let’s throw thousands of years of social evolution in the bin cause some billionaires can afford a lot of computers and exorbitant wages to have unscrupulous randos monopolize our exposure to the world. Ok
Same with FB, Twitter; I’m not finding a need to connect to everyone over their cat pic firehose, and the noise.
Edit: email works great for connecting to academics all over. Networking isn’t just through LinkedIn (which I also don’t use), and Upwork, or www at all. It’s just one of numerous conventions.
This was certainly true 10 years ago, now I can't really tell the difference.
