Yes, I like reading over past posts to kind of keep up with things. Over time alot of the same topics that have slipped into the past are posted again in a new thread. I find it interesting to compare the old with the new, if that makes sense.
In most of the Christmas groups I'm in the topic "What is your favorite Christmas...song, movie, smell, memory, etc." is started as a new topic when there is already a thread that has fallen back far enough to be forgotten. Call me sentimental, but I do like to compare the old and the new to see how we change, or not, each time we respond.
