When you build a website (for example, a site to connect sellers with buyers) which mostly relies on user generated content, how do you tackle with the below situation?

"User will not be coming to your site when there's less/no content. But, Content will not be generated when there's less/no user."

What would be the approaches to grow content/user base?

Based on my observation, most of the web startups are using either PHP or RoR or some other platform, but not Java. I haven't come across a single startup which is using Java for web app development.

1) Is it because of the lack of hosting support for Java based web applications?

2) Or, are there any serious performance issues when Java is used to develop web2.0 apps?

3) Any startups that already successfully using Java?
