Imgur is another example that gives users a lot of content without a login. I've been turned off by Pinterest because when I hit it through a Google search, it wants me to login. Instant back button. This is probably too generic a question. Depends on domain and competitors. If you could create a LinkedIn competitor that did not force you to create and account, I would use that. But if you can get that much content, it probably doesn't matter whether you force people to login or not.
