When analyzing these stats, there are several things to keep in mind.
1. Short periods of time can be very misleading. Short term fluctuations can make numbers look better or worse than they are. For example, things like bad weather can reduce publisher counts temporarily; the month ending on a holiday can slow down the mail, causing some figures to be included in the following month; temporary initiatives like activating inactive ones can inflate numbers. So, you must look at longer periods - several months at least, and compare them to the same months last year.
2. Watch out for fluctuations caused by reporting changes. The 15 minute publisher rule will increase the number elligible for counting without actually increasing the size of the org.
3. Sept 11 may scare a few people to activity for a while, but it will wear off.
Overall, watch the most important numbers - baptisms (which are seriously in the toilet) and defections (which are not reported).
Also don't forget that pioneering is down significantly, even though the hour requirement was dropped.
