Not bad. Especially having in mind that this is the second time around. I uploaded an updated version of the presentation, that didn't work too well, so I had to delete the old one and reupload. As a result the stats and faves of the previous version were lost 🙁 Some sites, like Ajaxian, are still embedding the older version so the stats are really not accurate.
Slideshare is a great service nevertheless, just like on youtube, you can spend hours browsing people's presentation slides.
