You don't type a semicolon at the end of each line. You type it at the
end of each statement. There may be more than one statement in a line, or
a statement may be split into several lines, and for example function
definitions are not ended with a semicolon.
Anyways, semicolons are seldom lost when you post a response to an online
blog post.

Some editors also might convert spaces at the beginning of lines to tabs
(or the other way around) if you are not careful with the settings. This
doesn't really matter with normal programming languages.

Why? Try some editor which is able to color your code, use it for a few
weeks, and you'll never switch back.
It naturally depends on the specific language, but with some languages
syntax highlighting and autoindentation actually help to catch typos as
you are writing your code. For example, if emacs starts autoindenting in
a completely crazy way, I immediately know that there's a typo somewhere
(maybe a missing curly bracket or semicolon). Likewise if the code gets
colored completely wrongly (for example if you forget to close a string).
Not that this happens often, but when it does, it's a great help.

In many advanced editors you can configure how the autoindentation works.
For example emacs has quite a lot of configuration options. (Of course that
doesn't mean it's *easy* to configure.)
It's just really handy when a line is wrongly indented, I just press tab
(regardless of where the cursor is on that line currently, and regardless
of whether the line was indented too much or too little), and emacs indents
it just like I want.
