Laurie -
At least you have your regulars commenting in your TR every day! That's more than I've got. Some of my people often disappear for long chunks of time, or only pop in to say something once a month. Sometimes, when people do pop in I can tell they have overlooked the last posts I put up - and I may have spent all day working on those posts (because of my stupid PC trouble). A lot of people also just prefer reading and not having to comment.
The other thing I noticed - and this is a major factor in people commenting or coming out of lurkdom - is the fact that there are many other holiday TR's going on right now, and most of them are also photo-heavy and/or detail-driven. (In fact, I just saw a balloon picture like yours in another TR a couple of days ago!

)
If your TR were the only holiday TR happening right now, you would have all the people who wanted to read a holiday TR coming here. But with so many active 2012 holiday reports going on at the same time (by Bret, by danimaroo, by pixleyyy, by me, and others I am not even mentioning but there are more and there will be more), the active commenters/readers are probably in holiday overload, so they stick to one or maybe two reports because that's all they can handle.
I noticed this last holiday season too, which is one reason why I kind of hung back and waited for everyone else to finish their 2011 holiday reports. By the time I started the December 2011 report, no one else was doing a holiday TR so it was more of a novelty!
So I finally realized that I have to just worry about finishing the TR so I can get it done for my own sake. That's the goal. If people are going to pop in, they're going to pop in. Otherwise, I'm doing it for the lurkers out there!
By the way - a lot of that stuff that you took pictures of at the Jingle Jangle Jamboree was not there when I was there in November, but it is the same exact stuff that used to be at the Reindeer Round-Up. So, when I went to DLR on 11/12 they had put up some things - a lot of things, actually - but all of those extra little details (like the barrels with the reindeer names on them) from the old Round-Up were added to the Jamboree after 11/12. I looked for them on 11/12 and was disappointed they were gone. I am so glad to see the little countrified Christmas touches are back again!
