The new streams may be part of it, but I still spend time in the main. It's also summer for most of us (not sure how many members are from below the equator) and I am super busy myself. I have to plan my memes ahead of time as I am busy with yard work, fishing and work. (Work has got so bad that I had to tell them no more coming in on my days off for meetings) Come fall it may pick up again.
SIde note: You and I tend not to agree politically, but I like a lot of your advice memes to your son. Also you occasionally slay it in Fun with some killer jokes.
