Didn't it go through a popularity cycle? It seemed to get sufficiently well-known that outsiders and tourists (including me) started turning up, so the core membership of PL theory insiders quietly disengaged. I think there may also have been an element of exhaustion: the regulars had debated and discussed the big, obvious issues pretty thoroughly and there wasn't enough news to keep activity at the same level. Also Ehud Lamm's attention seems to have shifted to other things for his own reasons, too.
