This question asks what the downsides are to hammock camping, but doesn't really address the reasons why you would want to sleep in a hammock to camp.
Let's say I'm backpacker new to the idea of sleeping in a hammock. What are the advantages of a hammock or reasons to choose it over the traditional tent and why? In other words, in light of all the problems with hammock camping, why do it in the first place?
Please be descriptive and pictures, where relevant, are worth a thousand words as they say.
