Thank you Darko for the research and I understand I should not complain about something I am getting for free, but I was rubbed the wrong way with the way you chose to distribute this—I was first asked for an email id, then sent an email with another link (I was expecting a PDF in the mail or at least a link to the content), this link then went to a page from where I could get another download link for the content, which turned out to be barely 1.5 pages.
I presume this was all done for analytics and for potentially harvesting email addresses to make a subscriber list.
Your privacy policy states—"We only ask for personal information when we truly need it to provide a service to you."
I am pretty sure there was no need to collect my email for linking me to a file that exists on your server for free distribution.
I am not trying to pick on you, but every time we have a post here on HN about FB or companies doing any sorts of analytics, we have lots of righteous indignation about how server-side analytics is enough and this and that. And yet, here you are, an individual (not a megacorp that needs to show quarterly growth) who effectively did something similar.
Anyway, after all this, I finally got a 2 page PDF with a small bulleted list with just the number of founders who vouched for every channel. The channel was just mentioned in a few words, so it wasn't always clear what the channel meant.
The PDF was so small I first thought you were only distributing the table of contents as a teaser.
