As readers know, I use Slideshare a lot - I was one of the very first users of the service (there was once a time when most presentations on Slideshare were mine!) and use Slideshare as an integral part of my presentation pages. So something like this is a worry - Lucy Gray saw all of her Slideshare presentations deleted and her account closed without notice or explanation. She has backups (phew!) but it's a major inconvenience. What's concerning is how arbitrary this was. Now I'm thinking seriously about a way to create my own embedded version of my presentations - anyone know how? - and dumping my Slideshare account.
