i didnt take what you said as negativity (more like a suggestion), but other people might've, so im not so sure.
to answer your question: i believe that it differs depending on whom you ask. me, personally? i would make a skin or whatever announcing "400 sub goal" etc, and that's what ive done in the past. some would maybe celebrate by making a public post (since i dont think youre allowed to make blogs solely for that kind of stuff), and that's the case for OP. to each their own, pretty much.
