"Developing for MySpace is tough because the platform is still not stable; it has many issues and bugs which remain unfixed for months," Lubarsky said via e-mail. "In its current state, the platform doesn't give enough confidence to developers."

He considers the Facebook platform, for which x2line has also built applications, much more solid.

However, MySpace has done a better job than Facebook of being stringent in its application approval process, Lubarsky said. In addition, the MySpace audience is more attractive to advertisers than Facebook's because it is larger in the U.S. and because its members are more likely to spend time playing games and decorating their profiles, he said.

For these reasons, MySpace applications offer a very attractive revenue-generating opportunity for developers, he said. "The audience is the main asset of MySpace," he said. "[And] MySpace isn't as saturated as Facebook with apps and [it] has higher-quality applications."

"Hopefully, MySpace would overcome obstacles and the platform evolves," he added.
