I'd noticed 11:11 for some time (I have a phone with a clock that stopped right on 11:11). I tend to notice my own birth date all the time: 11:17 (always glance at the clock right then). A friend-client introduced me to a group:
http://www.1111angels.com/ who puts out a mailing list. Their info tends to point to certain lessons--either my noticing the lessons they talk about creates them in my life--forcefully!--or it is all just synchronicity.. In any case they are fully devoted to raising consciousness/rememberance of spiritual truths
