I am usually not a big joiner, I would rather lurk or observe...but I really like this site! I haven't read through all the messages on this thread, but I would say that I am very technologically savvy (I love to learn new things and I have always worked in offices.) I am VERY busy (typical ISFJ), but I enjoy learning about myself.
It's interesting because some of the ISFJ traits described here fit me right now, but some I used to have alot more when I was younger (I'm 34.) I chalk that up to the years of counseling I've had and consider myself a more emotionally healthy ISFJ (I actually scored higher than 80% of the population on an emotional intelligence test.) I am not needy and I can be very assertive in a situation that calls for it. I am not afraid of conflict, but I do like to resolve conflict as quickly as I can, because I don't like bad feelings between myself and other people. The other stuff totally applies - responsible, dependable, hardworking (what I like to call somewhat "boring!) My husband is an INFP and I envy his ability to be spontaneous and creative.
Interestingly enough, I made my best friend take this test recently and she is an ISFJ too. I love her to pieces, but I never would have guessed!
