is quite interesting. Could be a next twitter, "PinIt" is now
next to Facebook and Twitter share icons on many web sites.
That is assuming enough people care about photos.
And they do, making facebook biggest photo storage.
I find in particular interesting Pinterest's GUI.
It is quite simple, but efficient, with vertical columns
to utilize all space and preserve proportions of photos.
Vertical scrolling is natural for web.
Should Windows 8 Tiles pages be like that?
Problem with "metro tiles" is (lack of) efficiency.
Google and Bing images searches do similar but with horizontal bands, so all images have same height, but there is no space for text. Being web sites, they can change design any time,
but an OS like Windows 8 is much harder to change.
Should not be, but it is.
Anyway, "social photos" on Pinterest are great.
