Agreed. In the first picture, you can see it stands for "Java FlightRecorder," but there's no explanation of what that is or does. A profiler?

Second this. Even when someone said it was in screen shot, it took a minute to go back and refocus to find it.

But. No knock on this guy. I find all STEM writing could be helped a little with some up front what/why/how in introduction.

I want to dig this, but on first scan through, I have no idea what this is doing or why it is cool. So, for getting an article out, if I'm a casual that isn't a die hard user of JFR, then what makes me want to dig deeper? Of course, maybe the goal isn't a wider readership.

I linked now to articles that provide you with more information.

I did go look up JFR when I had no idea what it was. I was just trying to give them a gentle suggestion that explaining the tool, even in 1 sentence, would be helpful.

Thanks for the feedback, I added a small disclaimer at the beginning of the article, telling the reader what JFR is and where to find more information.

That's perfect, thanks!
