Your source code says it all. When I "view source" there's one single line of sourc edoe, followed by this HTML comment:

W3 Total Cache is minimising your HTML code so that you use less bandwidth and serve the code faster (actual variations with this will vary, but most times it's really not that noticable to humans with a standard page).
After answering that part I have one big question - Why does the formatting of your source code matter? The only people that look at that are the code geeks (like a few of us), and if we want to see it, we'll be able to know what it does without the formatting anyway. As long as your site validates using the W3C validator, what the HTML code behind it looks like really doesn't matter at all.
The 'robots' META tag is also another thing that's really not needed. The robots will index your content unless you ask them not to, so adding in an extra tag just to tell them to do what they were going to do in the first place is just bloating your sites source code anyway.
