Possibly, somehow this update makes it seem they are passively telling us that they do not want our suggestions and just quietly accept what they give to us only give feedback to bugs. I don't even know what the hashtag for "presentation" should represent.
but seriously, i am guessing that maybe of the korean language translation, it is possible that #presentation would be the same as #suggestion, since you have to present your opinion or proposal to a group like in company meetings. Then again i am still speculating.
they should also fix the layout setting, have to make 2 spaces in between paragraphs for it to appear as a normal spacing when the post is submitted.
