You're not quite alone anymore.
For roleplayers, roleplay has typically been restricted to whatever realm you happen to choose. Some roleplaying realms are far more populated than others. This means that new roleplayers tend to flock to these realms as well -- after all, if you're looking for roleplay, you want to go where the roleplay is at. However, after the release of patch 5.0.4 the dynamic of servers has changed a bit, and it spells some really big changes for roleplayers and how they look at the world.
Cross-Realm zones are a new feature that was introduced in patch 5.0.4. They're starting gradually at the moment, but more realms will see this feature implemented as time goes on. For roleplaying realms, a quick trip to Dalaran, Shattrath, or any of the more out of the way cities may reveal a surprise to traveling players -- your server is now linked with another roleplaying server. Or maybe even two or three of them, depending on the area.
Inadvertent or no, this new feature is a tremendous boon to roleplay.
