agave nectar

I've heard sugar is supposed to be bad for our gut....not to mention our weight. A friend of mine with different problems has been using agave nectar in place of sugar.  She gave me a bottle of the light and a bottle of the dark. The light is similar to honey. The dark is similar to molassis (sp?). Anyway, I was wondering if anyone here uses agave nectar in place of sugar and if so, what are you thoughts? Any good agave nectar recipe sites?

i use it, along with honey and maple syrup. i find it sweeter than honey so i use slightly less than i would if i used honey. my honey is always crystallized but the agave nectar is liquid so i end up using agave nectar more just out of convenience. but then i use all these natural sweeteners very sparingly, in small amounts and then not every day.
