How many times have you heard, "will your slides be made available after the presentation?"
To the rescue comes Slideshare.net, a very slick presentation sharing service that helps folks get their preso word out quickly and easily. It's got tagging, most popular, recently added, and the rest of the stuff we expect in a sharing service. Think YouTube for Powerpoint.
To test it out I uploaded the PPT file I used to create a recent JotSpot developer tutorial. It worked flawlessly -- check it out.
While the original full tutorial includes voice-overs and animation thanks to Articulate presenter (would LOVE to see this capability added to slideshare.net btw), the ease of use and instant gratification of slideshare is very compelling.
