From Paul Hami's blog: Here's a quintessential free Web 2.0 application that consists
entirely of user-generated content that is shareable, searchable, and
often downloadable. As its name suggests, slideshare hosts slideshows;
and anyone can create a free account and upload to slideshare. Uploads
can include PowerPoint, pdf, or OpenOffice (odp) file formats.
Uploaded files on slideshare can be tagged to facilitate topical
searching. As well, slideshare facilitates comments, favorites, etc. It
also provides forums for specific communities built around shared
interests.
This summer, slideshare became even more powerful by introducing the
concept of "slidecasts". You are now able to upload audio commentary
and/or musical accompaniment. The audio file must be hosted elsewhere
on the net, but this isn't difficult to do, and there are several sites
where audio files may be hosted free of charge. Our Media and MediaMax are two examples.
