I think I am a very interesting person, but my interests are esoteric that I understand why many would see me as boring. I personally don't find NTs dull, but it's understandable why they wouldn't find me interesting. It probably just depends on the person's definition of boring. I prefer excitement in very small quantities. In fact, an enjoyable life to me doesn't consist of traveling around the world but rather having a comfortable home waiting for me at the end of the day, living with someone I love, and making sure ever moment of my life counts. I find people who are always on the lookout for any kind of instant gratification boring; for example, someone who can't stand movies with thick and elaborate plots and would rather get the instant gratification offered by an adventure or slasher movie. I value depth of breadth by far.
I might be boring but I can't remember the last time I was bored. I always find something interesting to think about or do quietly by myself. I think sometimes people don't understand that I am not always in the mood to be "entertained" by others and would like to be able to sit by myself without being interrupted. I like to sit in the lobby at my Res Hall and do my homework, but I can rarely do it because some many people come up and talk to me.
I've been told I was boring due to my passive nature. I don't like to argue or debate; there's no point to me. I would rather be informed about someone's view and not attacked. I love to listen to people's thoughts and beliefs, but I don't like it when they remain close minded to other possibilities. If you are going to tell me your view you should be polite and listen to mine too. Debating is a win/lose situation and having a discussion is a win/win situation.
I think what bothers people the most about me (and possibly many other INFJs) is that socially I am available and fun to be around, but when these same people want to go to dancing or to a big party I really have no wish to participate. Tons of people I don't know? Loud music? Drunk people stumbling around? Not my idea of fun in any way. I am always within reach but never available.
All-in-all, I find other NFs very exciting to be around. I don't think they are boring people.
And just for the record, I like WWF, but not as much as I like watching Muay Thai.
