Do you learn from Twitter?

I don't know if this is just me, but lately, my primary source of finding great content is Twitter.

It began when I started to bookmark Twitter threads and found myself going back to them over and over again - every time I needed to recall something.

Do you feel twitter is a good source of finding great content to learn from?
And that it is hard to find great content on twitter? Eg. I did not know about David Perrel until recently.

PS: I am making a curated list of Twitter Teachers. Would love to know your opinion.
