Can’t stop getting excited of Slideshare.net. Today my slideshow about The perfect interface is the second most featured.
I’m also the most favorited slideshow today:
Well, enough boasting! ;-)
Eagerly I’m waiting for further developments like:

2. Exporting slideshows as ppt, pdf and other formats.
3. Online editing.
The only content-related web service I ever payed for is Flickr, but I would definitely pay for this also if they do further developments.
