Yes, it seems from recent research - by Susie Kearley, for example - that they have added a new factor: your regular readers' reads count for less, to undermine 'read-for-read' groups.
So if you have a bunch of say 20, 30 people with related interests, sharing pubs like this, who read each other's work, that FoM x4 is being slashed anyway, to maybe $0.01, 0.02/read.
How do you change back to regular tier, BTW? I had a look when feeling grumpy the other day (for a change) but there didn't seem to be an obvious, easy way to reduce the payment (again for a change).
