When it comes to the 'shelf life' of a piece of content, most algorithms work the same way.
Whatever you post takes a moment or two to pick up traffic, then it goes parabolic, then it dies down, then it nearly disappears.
This is always true, but like every rule, there are exceptions.
Sometimes old stuff goes viral again, generally because something related happened, and the old piece of content in question became relevant again.
But I think that sort of doesn't happen on Publish0x.
What I see on the homepage is always pretty 'fresh', I don't recall ever seeing anything posted more than one or two days ago.
So it seems to me like articles on Publish0x have a relatively limited shelf life, what's your experience?
