I received this email - as did a lot of other people:
We've noticed that your slideshow on SlideShare has been getting a LOT of views in the last 24 hours. Great job ... you must be doing something right. ;-)
Why don't you tweet or blog this? Use the hashtag #bestofslideshare so we can track the conversation.
I checked my Slideshare and the only presentation I have on there suddenly has over 30,000 views! I think they added an extra 00 or something to everyone's numbers and sent that Slideshare RockStar email! RickStars, more like ;)
It's already trending on Twitter as the number 4 topic. Really simple and elegant idea, lots of buzz and conversation created from it. Brilliant. And it plays with people's egos, so all the more reason to talk about it, they probably also saw a big surge in visits to their site. They must be LTAO ;o)
