I discussed this with "The Mayor". It appears that a lot of folks were traveling for the holiday and this disrupted normal posting. I know that it did for me. As for Al, he has been under the weather with a severe flu.
Posting seems to me that changes with the times. At times it is incredible with the amount of post, then slows and then regains momentum.
Rushmore has discussed this before.
I am sure that there are other reasons.
