Emojis are fine; they add some body language into our communications and sometimes (infrequently) that's really important. They also let us use symbols, and I've used those before 🔗 to what I feel is positive effect in punctuating a post. (Tangentially I've also been using the link emoji to make it clear where I'm linking to something until our links get revised 🔗.)
The real problem there is, like Pikalek points out 🔗, that text is fluff 🔗. Stack Exchange likes a high signal:noise ratio, and that applies to individual posts as well. All the formalities you might find at the start or end of a post (“Hi”, “thanks in advance”, “please help”, etc) are noise; remove them from the post with prejudice. Posts should be as close to 100% signal as possible, and it's almost always completely possible.
Would you rather read:
Hi everyone! I'm new here, still figuring this site out. Anyway so my question is, how do I foo a sprocket? I'm having trouble. The documentation isn't any help! Please help me with this!!!
Thanks in advance. Cheers, Doppelgreener.

The first is a problem whether or not it's also littered with emojis; those just make it even worse. Having to read posts like the former over and over (along with bad spelling/grammar) is what drove me to be a prolific editor. 😐
TLDR: Emojis aren't a problem here; fluff is; exterminate it so thoroughly it'd make Arnold Schwarzenegger impressed.
