It is a site for sharing slideshows. I like the concept. It puts slideshows in a nice little tiddy format instead of linking to a ppt file. And I guess if you are looking for some ideas, you could try to poke around. So I see some value there.
But what strikes me as funny is the language and presentation, with the Flickr, YouTube social software, web 2.0 spin.
The description says:

Discover interesting slideshows.

I think I may start the Excel spreadsheet sharing social network site. Think of all of the fun you can have discovering Excel spreadsheets, tagging them, and all the fun people you can connect with! Coming soon to a .com near you.
