Hi there,
First, I need to say I'm not an experienced cuber. I haven't been to a competition (will go to my first one in 2 weeks time) and my times are not at all impressive. I am however trained as a school teacher and I have a pretty good idea how to teach stuff to people effectively. So, I feel qualified enough to comment on your CFOP beginners tutorial. So I'm writing these comments first as a teacher and secondly as i cuber.
1. You called your tutorial the CFOP beginners tutorial. Technically, this is not correct. CFOP stands for Cross - F2L - OLL - PLL. Your tuturial does not include the F2L step as it solves the corners on the 'cross layer' and the middle layer edges in 2 separate steps, rather in 1 step like in CFOP. Therefore, your tutorial is not a beginners CFOP, but a LBL method.
2. Use sub-headings. That would make things much easier to read and to go back to things I you haven't understood them. Also, it helps to let people know what the step is. For example, in the second paragraph, you start with "This is the quintessential first step". But what is that step? It's only 2 lines later that I find out that that step is the cross. If you make a heading saying: Step 1: The cross; everybody will know what step this is and can return to it later. Now they have to search the whole text. Not a problem if it's at the beginning like the cross, but it will be a bit tedious to run through the whole text if you wanted to find a specific OLL pattern and don't know where to find it.
3. Make proper use of paragraphs and sort them by theme. For exampe, when you're explaining the middle layer edges, you start with explaining algorithms and cube notations. Then you start with a new paragraph continuing explaining cube notations and in the same paragraph you suddenly switch over to explaining how to solve the middle layer edges. My suggestion would be to make one paragraph about cube notation and then start a new paragraph explaining middle layer edges. Also, put algorithms in a separate paragraph in bold, so they are easy to find.
4. Make use of punctuation marks in a way that make things clearer, even if you have to violate grammar rules. For example, in the bit about middle layer edges you wrote: "if the colour that was on top lines up with a center..." It took me a while to figure out that you didn't mean top lines as in lines on top, but top lines up, as lines used as a verb. If you would have written "if the colour that was on top, lines up with a center" that would have been much easier to understand. It may be grammatically dodgy but it makes your intention much clearer.
5. Use visualisations. You only have photos of the solved state of each step, but it would be helpful if you could include photos of the steps in between. For example, again with the middle layer edges, I was really struggling to figure out what you meant. You've done it with the OLL patterns, so why not in the middle layer edges?
6. Your middle layer edges explanation was very difficult to follow and I think unnecessarily long. It took me several reads before I figured out what you meant and came to the conclusion that it could be much easier. What you want is to find a middle layer edge in the top face. Then you look at the colour on the side face and align that colour with the center piece of the same colour. Make sure you turn the cube so you face the face with the edge you want to solve and perform one of the algorithms you gave. The whole story about squatty Ts, corresponding edges, which face is next to which face, etc, is completely unnecessary at best and is quite confusing. For example, becausing you started talking about working on the red face as an example, I was under the impression that then you wrote: "make sure you have to upside T right in front of you" you meant to T on the red face. Of course the "upside T" should have given it away, but still confusing. If you had said "make sure the face with the edge you want to place in in front of you..." that would have been easier to understand.
Now some minor stuff but useful.
- Make the cross on the white face. Of course, this is not a hard and fast rule and everybody has their own preference, but most people tend to find a white cross easier to work with.
- Make the cross and the first layer corners on the bottom. This avoids the necessity to use D turns with your pinky. If you have your cross on the bottom, you can use U turns instead, which are much more comfortable to perform.
Finally, if you want to find out how good or bad your tutorial is, give it to a friend who's never touched a rubik's cube before, along with your cube and let him have a go at it. If it takes, let's say more than half an hour to get through it, you'd probably need to change something.
Hope this helps. I'm not trying to dish your tutorial. I'm just pointing out some things you could work on.
