A post a day means the heart's still beating.
NB gets a couple o' thousands.
If that's dead; I'm a Biker Mouse from Mars.
If that is dead then I'm six feet underground.
On topic:
A lot of people have been asking what will happen to NB when Naruto ends, but we cannot know for sure, can we? Asking about it is rather pointless because you know what the answer will be. Some will say NB will die, others will say it survives, but there is only one way to find out. Only time can teach us.
I do think that NB might be less active, but there are enough members that will still enjoy the forum and rp, thus it will stay active imho. Other than that there are always people who start reading/watching Naruto, or have not finished it, and might feel the need to talk about it on the forum.
