I submit Exhibit F:

Yet Another Fucking Login Prompt. I saw Shapeways on Mashable and thought "hey, I would love to fabricate some gears, and maybe some other stuff", so I go to look at their site.
But nooooooo, you have log in. Does no one understand that I (and everyone else) have a thousand fucking logins to every site in existence? Do I really need to login to BROWSE your site? That's ridiculous.
I hate your site, I hate your stupid login prompts.
