You're not alone. Terry Mattingly has just written about the way in which denominations in the States are facing these issues, but adds an interesting slant to the problem: liberal and conservative Jews are facing exactly the same issues. As he notes:
Conservative Judaism’s membership rolls are in free fall.According to a strategic plan for renewal issued in February by the denomination’s congregational arm, the number of families served by synagogues belonging to what was once American Judaism’s leading stream has shrunk by 14% since 2001. In the denomination’s Northeast region, the number of families has dropped by 30%.
And liberal Jews are in the same boat...
Mattingly nicely sums up the issues amongst both Christians and Jews as: the post-denominational mess.
