"It's easy to criticize when you've never worked on the kind of infrastructure that Gluster has. "
It's easy to critize if I've ever done one essay, research paper, marketing piece, commercial project... many things where I took the time to document and explain what I was presenting. Often in an ad hoc was as it was a secondary focus. I don't have to work on a specific product to understand a common skill or requirement.
"Here's the fantastically informative website for the Linux kernel."
"based only on what I can get by clicking around on kernel.org? I could come up with similar examples for many features on Apache or Mozilla or OpenStack projects as well. "
You cite an example from a group that famously doesn't give a damn what people think which also expect people to know what their project is already. Also an outlier in general. Then some others whose sites at least explain what they do with key features. Unlike Gluster. You grasped at straws more than I expected.
"Hey look, that's exactly how it happened when this was part of a project I was doing myself."
You did exactly what I'm asking them to do. More actually. Your site supports my position albeit half the links in the paper/slides set didn't work. Maybe it's NoScript but one or two told me what I needed to know. How about some examples of how easy it is on big, collaborative projects:
https://www.freebsd.org/about.html
http://www.xtreemfs.org/all_features.php
http://toolkit.globus.org/toolkit/about.html
https://owncloud.org/features/
(OwnCloud since the OP blog post mentioned it as a competitor.)
"But none of that has anything to do with the original point. "
Your original point was that the author should've been responsible enough to do research, identify key features of Gluster, and consider them before making claims in the post. You also argued against Gluster site author(s) needing to be responsible enough to identify the key features and list them on the website for people like author doing research. You then made excuses for them despite that being quite easy and considered good practice. So, I'm addressing both the poor research by Infinit author and poor docs by Gluster that contributes to it, along with your double standard on the topic. I'm adding counter-examples to sites in and outside their domain with varying organizations and team sizes to show how they could improve.
Had they had good materials to draw on, I'd have never argued with your claim that author should've known what features they do or don't have. Or maybe if you slammed them for irresponsibility as you did the author. Seemed to be a bias, though, along with OSS documentation problem worth noting.
