It needs to be very clear from what and how you're presenting information the quality, source, and rigor of your data.

This blog post is pretending to be true.

I want to contrast it with this: another startup(ish) blog post about their own data

https://www.backblaze.com/blog/hard-drive-reliability-stats-...

That is a wonderful, useful, trustworthy source of interesting data.

The post source seems like made-up marketing fluff pretending to be real information. I'm looking at graphs I entirely believe were made up, I have nothing to support the conclusions, and I'm very concerned that a less wary reader would think it's true.
