I was merely speaking of anecdotal experience (and an example that I could give) for things other than just forums, and as a domain name investor.
A perfect example of this is Covid-19:
The domain name Covid19.com
whois:
The domain name Covid-19.com
whois:
Someone was able to scan the news and immediately register that term. They could also be doing it for hundreds more each year to catch that diamond in the rough, but the flip of that domain alone would've been 6 to 7 figures, paying for all others that might only go for 10s to 100s.
However, you have to know what you're looking for with trends and have multiple registrars that support API registrations to pound them all at once to grab the domain.
It can work, but it might not work; in this case, I could probably very much so say that it did work.
As far as forums go, I did have the intention of using UnmannedForum.com
for drones during the "drone invasion" for sightings/reportings (that would get censored/shadowbanned elsewhere). But, I didn't have the infrastructure in place to pop up a forum to fill it with content that would be engaging enough, like a forum should be (like using ChatGPT to recommend Category and node names based on the trend, automatically create them, create users to populate from sources, etc.). It's still going to be used for drone discussion, and perhaps UFO sightings in the Off-Topic/sections. But, you shouldn't chase emerging trends for a forum unless you can get it up within hours (lesson learned to build that out for forums, as I have for blogs).
