Who is on Slideshare?

• Since it is still a beta application, most of the early adopters tend to be tech types, as measured by the content of the slideshows.

Advantages

• Connects members through interests in sharing and distribution of visual media
• Multiple modes of interaction; sharing, joining groups, pings, comments
• MySlidespace for saving of slideshows, contacts, uploads and messaging

• Slideshow is missing creator's "voice"; transcript needs to include creator comments
• Bias towards tech crowd as content not for everyone, starting to branch out to include photo essays, humour slides
