A minor issue, but to me like fingernails on a chalkboard, is the grammar.
The fourth bullet point contains the line

Can you imagine how many people will see this web page. Billions and billions? Perhaps. For that size audience, it is worth proofreading, in my opinion.
A more significant issue concerns who is the target audience of this web page?
Certain phrases will be understood by almost anyone who speaks English and has
used the web for more than a couple hours (e.g. try again later or
make sure it is spelled correctly).
But much of the above web page requires a technical background to interpret.
Could it all be written for a complete beginner? Yes, but it would probably have to be quite lengthy, which in itself is bad.
So addressing this issue adequately is quite a non-trivial problem.
