Conversation is a team sport, with a minimum of two players. A "boring" person can be characterized as someone who does not contribute interesting anecdotes or facts to a conversation, or asks no interesting questions. Like most team sports, a bad player can be "carried" to victory by sufficiently good team. So while it's certainly possible that you were talking to boring people, a more actionable and probably more rewarding point of view to take is that you were being boring, and strive to learn techniques for making a conversation more engaging for you and your team.
