Personally, as I get paid to write in certain places, I will be using the WordPress post timestamp facility a great deal and attempting to pre-load as many articles as I can manage. This time of year my family will be wanting to see me more than the customary back of my head haloed in a computer screen glow!
While the timestamp feature is a life saver for anyone who will be mega busy over the season, remember you might still attract comments that will require attention, either spam busting (spammers never rest) or replying.
If it you will not be otherwise engaged then you can make good use of the seasonal slow down to get some housekeeping, research and heavy lifting done. When the blog world is not paying quite as much attention is a good time to do anything risking, service disrupting or potentially embarrassing changes, such as trying a design change or moving platforms.
So that is my plan, what will you be up to over the next few weeks?
