Short and to the point.

I like it. Like @cowboyd, short and to the point.

The title is "why laziness matters in Effection", but the post starts with a promise, which suggests that the title has wrong scope. Maybe something like "why Effection operations are lazy"?

The thumbnail needs a bit of clean up. To help tease out what the thumbnail should say, can you answer

1. what is the thumbnail communicating?
2. what should the thumbnail communicate?
3. what would be a better way to communicate the main point of the article?

"Why Effection operations are lazy" is a much better title.

The thumbnail should communicate calling != running. I think a better image should represent the flow as stages, I'll update it to communicate that clearly.

@joshamaju Still looks like the preview deployment is messed up somehow

@joshamaju not sure why it isn't working, but this is the url that I'm seeing https://extraordinary-dango-a3ed41.netlify.app

Is there a different one?

[joshamaju]

Right. Anonymous deployments are short lived.

[cowboyd]

Is there a way we can get it to re-deploy. Everything looks good, but I just want to do one pass with it actually rendered. If we can't bring back the deploy in a more durable way, I can just check it out locally.
