I know that it's all the rage in 2016 not to document products and rely on inefficient, inaccurate, poorly-written user forums to document a product. But in Alfred's case, I think it's a big mistake.
From what I can gather, Workflows are quite powerful. And indeed, you've expanded them significantly in Alfred 3. But for those of us who aren't currently programmers, the documentation is virtually nonexistent, so we just don't use them. There's one overview page saying "here's what trigger/input/output are." Then the next pages are getting into bash script construction, instantly dropping to the level of discussing variables and control structures.
But for those of us who aren't bash programmers, who don't understand what workflows do beneath the covers, how variables are used, etc.
I think Alfred could be boosted to even higher success if people really understood and could access its power. But I'm a power user and I can't figure out how to access its power with a modest level of investment. I doubt other non-power users are able to either.
