Compost fail?

So the compost bin is full and it looks like there is lots of actual compost in the bottom (I know this is silly but it feels like I did magic or alchemy or something!) There is also a very recognisable potato plant growing out of the door at the bottom, what I think is an ant colony and a couple of dandelions growing out of the top.

I don't mind the potatoes growing there, that really is free food.
I couldn't really care less about the ants although I'm pouring some water in there more often (I leave a bucket next to the bin to catch the rain) because apparently the ants suggest the compost might be a bit dry and I think I would like them to move on before barbecue season.

I'm a bit less impressed by the dandelions.  I may have thrown some (about 100) dandelions in there without really thinking it through.  Next year I'll put the dandelions in the council compost bin instead - and I'll probably have a field of dandelions instead of garden.

Maybe I'll learn to love them, they're kind of cheerful, need no work and can apparently be eaten.
