I get confused several times, especially in speaking English, when I hear more and more native English speaker prefer to use "be doing" form. When I attend a class the instructor may say "We will be talking about XXX in this class" instead of just simply saying "We will talk about XXX in this class".
And I see this today:
I’ll be showing you how to make a simple Chrome extension dashboard from scratch.
from this blog. I thought that would just be simply:
I’ll show you how to make a simple Chrome extension dashboard from scratch.
So why do they bother to use the future continuous tense when they can just use simple future tense?
