My experience has been that it's not so much the number of followers a publication has, but how they publish new stories.

Some of the big pubs "mass publish" in the mornings and a whack of stories go up all at once. The writers at the beginning of that queue get no visibility. They're on the publication page for a split second and then they've scrolled into oblivion.

I'd much rather be in front of 1000 people who actually see my post than 270,000 who never see it because of the volume published.
