Chana has posted her [as usual] incredible notes from the YU & NCSY dinner. It's fascinating in a number of ways, from how they approach kiruv to addressing some of the criticisms aimed at them to some of the difficulties they run into to simply discussing their own experiences and ideas. It's worth taking the 10-15 minutes to read it; it's a tremendous insight into NCSY.
I did find interesting the acknowledgment of the limitations of NCSY and, really, most kiruv organizations: Follow-up. Keeping that strong connection going after people have moved past the stage where NCSY et al are making their impact. I think that's one of the strengths of BeyondBT, which started to try and fill that gap, and is having a nice small impact in just a couple of years.
