It is true.
When I started threading as an art form I would get inundated with "Nobody reads threads. Say it in a single tweet or write a blog post."
The other is, turn your links into threads.
And even though most people will miss each drop, some people will see, interact with, and share a drop that breaks through.
So far as I know, my most popular tweet on this site was a lone tweet, not a thread.
But I can get a thread to go viral so much more easily than a tweet.
I can get a thread in front of my followers more easily than a tweet.
1. Make sure the subject/title/name is in the thread, not just in a QT or a LRT.
2. Thread it.
3. RT it and/or bump it at intervals
If it's not a thread, it's too easy to overlook.
If you say it only once, it only has one chance to catch fire.
