Thinking "how much company would pay for that" does not get me excited either. It been proven over and over again (through different social networks) that just because my friends likes something, it doesnt mean I will like it either. It neither means I will be more reluctant to try it out. "Like" on its surface does not prove me much information, and most FB users know it by now. Example: if someone "likes" chick-fil-a, what does it means? Does it mean they prefer chicken over beef? Does it mean they love the company? Or simply they are an employee of said company and want to look good in case their employer peeks on their wall? Or maybe that they support c-f-a's Christian roots of not hiring gays? Or perhaps because they hate humanity at all and they love that c-f-a puts aluminium and MSG into their food? "Like" alone does not mean "yes go eat here and spend your money its worth it".

Edit: I think Glass actually solves a huge problem with mobile for FB/Google/MySpace/etc: displaying ads. Right now, they make virtually nothing from mobile users, which is a threat to their company as more people use their phones/tablet/etc to access the site. With more screen space, they would easily have room for non-intrusive ads, and ads similar to what is displayed on the desktop. So they should be able to fix their problem with mobile.

Who's problem is that? I have never heard a user complaining that only 2 ads fit on the small screen. Have you?

So poor FB and Google have a problem because they cannot fit 50 ads on the screen. What a shame, they cannot make another $10 billion a year. To solve their problem we will wear some cheesy glasses so we cannot escape ads. Get what I tried to say? The glass solves Google's ad "problem," if but only if enough users become Glassholes. But why should they? What problem do they solve for average Joe that cannot be solved by iPhone or Android or W Phone? None

These glasses solve absolutely no problem for most people, you can glance at directions on your smartphone and walk for 200 yards. Rinse, repeat. This is an ad companies' dream and could be used in specialized fields but that's about it.
