Yes I noticed this too and was quite perturbed by it. Hopefully that gets fixed, because it must be an error. I also noticed before, though, that in the 'blog' section we were seeing a bunch of comments instead of top-level posts.
Also, how did you get the little image in the title without markdown?
Yeah, I noticed the comments in the blog for a while too, which was annoying but now the solving of that problem has resulted in an even bigger one! lol Gotta love them unintended consequences ;)
The emoji? Yeah, just gotta paste 'em in. There are tons of them that you can use. Have a look at emojipedia.org
