is Marmite like Vegemite
Oh no its not, Marmite is far better than Vegemite.

Never ever taste Marmite on it own! Spread thinly on toast with REAL butter is the way to go.
I don't use marg or butter (to lazy to get another container out) and have the MM nice and thick on my toast, puts hairs on everything for you, and gives you x ray vision...

A thin layer on a toasted cheese sandwich (before toasting)
Second that, was brought up on marmite and cheese sandwiches for snacks, but if you put the MM and cheese on toast, then grill it, its Owesome...
