The troubles with Blogger site feed. A rant

Some of you will have heard my cries for help about six months ago, then again three months ago and finally today again. The reason: readers of my blog who wanted to subscribe, couldn't. I added the gadget 'stalk me via 'e-mail' button, to provide at least some sort of possibility to follow, but it wasn't what I wanted. I like it nice and clean.
Searching for an explanation via Internet left me puzzled. What I found were terms like feed burner (I might burn food, but I haven't got a clue what that feed burner thing does or is used for), redirect link(?), Blogger feed url, etc. I wouldn't know how Blogger feeds urls. I feed my animal and myself, and that works just fine. If I have visitors, I even feed them.
You see I love my facebook friends, because they rock. I posted my cry for help in the afternoon and had two people immediately replying, trying to help. Now Sudam, the wonderful man, is an IT wizard and that, you can imagine, left me with my head nearly exploding. I was even more confused after his kind help and the links he sent me.
Rachel, the lovely girl and I, we messaged back and forth until she had to leave and all the while I e-mailed with my friend Marcos (50 e-mails!) including screen shots on my side and finding solutions on his side. To no avail. I was devastated.
He finally started his own blog to find out how it's working, advised me to delete my blog url from that field and asked me to change 'full' to 'none' and back (saving between the steps. And don't ask me what that's for, if you did ask if I had a clue, I'd probably say exactly that: 'none', while I'm 'full' of anger.) So I did as he asked me and miraculously, the feed is now working.

But I wonder:
Why is there no explanation out there following the elimination process?
Questions like: if you go to your dashboard/design, settings/other and where it says Post Feed Redirect URL, is that field empty? Then it wouldn't be such a problem, would it? Best with screen shots. 
But no, all you get is an array full of terms nobody is able to understand, at least not this person here. I'm usually not that stupid with technique. But this tiny error of having my blog url in that field, kept people from subscribing.
At least it's working now and everyone who'd like to see what I'm up to, my rants or how the iguana is can subscribe. Wonderful world of Blogging, eh?
Thank you to my three brave friends who tried to shed light on the subject. You guys are awesome!

And to finish on a humorous note, this one here makes me smile every time:
