I don't think of myself as the average Tapas creator, but my buffer is usually 0. Technically it's usually negative, since I'm always behind schedule...
And on those rare occasions when I do have a buffer, there's no guarantee that I'll use it. Deadeye is buffered 20+ pages on multiple sites, but I still don't update because I just caaaaannnn't for some reason.
There's no motivation...basically, I don't feel like anyone will even miss it (which isn't exactly a delusion...). Plus, there's the despair that my buffer will run out eventually, and I'll have to post new updates to 4 different sites at once, which I caaaaaaaannnnn't even more...
