Firstly, Flash is installed on more machines than any other plug in, web browser, or operating system. Allowing users to join your science project without having to register, download, or install greatly reduces the barrier to entry.

Additionally, the OCG is not meant as a replacement to existing standalone frameworks (like BOINC or World Community Grid) but moreover as an extended computational and advertising platform.

For example, let's say you have a standalone application and also an OCG port. Your OCG application can say a message such as

"Hi there! As you read this message you are contributing computer power to our project. If you would like to help out even more, then click
here to download are standalone"

One of the most difficult obstacles for new volunteer grid computing projects is advertisement. Many projects have thousands of work packets and only a few hundred members. Because the OCG will be on Facebook, MySpace, and around the web, there is a greater chance for more users to join your project.

At the very least, the OCG raises awareness of your project and grid computing in general to a large amount of Internet users.
