Is it easier to develop a relationship online than in real life?

It seems to me there are different kinds of relationships online than in real life. In real life, there are many activities I can do, and I’ll meet people doing these things. Online, it seems different. Relationships are either about friendship or love or a particular interest. But they seem to be one on one relationships more often; not group relationships. It is easier to develop intimacy onlin than in real life.

Then again, I can argue against both those positions. So what do you think? What has your experience been? What data is your opinion based on?
