There is outrage over this on LBC. But I think its a really good idea, I remember the same outrage when they went to fortnightly.
We're a family of 4, we recycle, compost and avoid buying over packaged stuff and anything in plastic (especially veg and fruit!). As a result the bin only goes out once a month and often isn't full. If you don't have a garden then a weekly food collection pickup is available.
I see other people with only one or two people in their house and every other week their green wheelie is bursting. I know from times they have used ours that they put alot of food waste and packaging in the bin. We are rather wasteful in this country compared to just about every other European county.
