No you're not old, you are just not ridiculously young. :)

I agree though, use of emoji outside talking to your friend, to me, is an instant warning of immaturity, and a flag of more to come.

The OP post was horrendous to look at, I'm not sure why anyone thought that it would help with understanding the content.

I'm somewhat young (maybe ridiculously so). I'm not a huge fan of emoji and find this page very hard to read (why the hell do you need a pictogram to illustrate a word you just wrote?!), yet I think it's useful for efficient information transfer ("maximal accessibility") for documents to not purely consist of dry, plain walls of text. A few human touches here and there can be effective for navigation within a document through differentiation (not everything looking the same). Emojis in headlines are the easiest way of achieving that.
