Like Theodric said, a lot of people is locked out of the game thanks to the login errors and, those who ARE inside will be busy levelling up. Once the server issues are settled and people reach their desired levels, they'll start roleplaying more often.
With that said, the best way to catch some on-the-field or random roleplay is to emote in-character. That will be just enough to indicate to others that you are now on 'roleplaying mode' and that they can join in. You have to be patient, though, since some people's characters might not be ICly in the area you are at and, for consistency reason, opt not to join in. Not to mention that some will take some time while they decide how they want to approach you. Because of these reasons, you must not just drop one single lonely emote but two or three before moving on.
To increase your chances of success, you can emote around people who have lore-friendly names.
You can also try taverns and inns. Tons of quest send players to those locations, so chances are -someone- will be a roleplayer. The problem is knowing if they are willing to interrupt their levelling for the roleplay.
