Many clips are collections of news footage or tributes to those killed. Some users are seen venting into their Webcams about the shootings.
One of the most-watched videos is a song by Kojo Best that's dedicated to the families of the 32 victims.
Still, several videos have drawn criticism from the online community. A number of users have posted videos that are dramatizations of two of gunman Cho Seung-Hui's violent plays. In at least one video, the costumed players are barely able to keep straight faces.
Comments on the video show that some users don't think the plays are any laughing matter.
YouTube says it leaves it up to the community to decide what content is inappropriate.
