Feed settings.

I'm always moaning about how cr*p the feed is here. I see the same posts by the same 20 or do peeps for days.
However....
Ive fiddled with the settings/ sliders this morning in the hope of seeing a bit more content from differents users and different groups........and ya know....it worked!
And.....
I'm already realising theres so much content here I'd really rather not see......
