Weird Habits of LJ

I've noticed over this weekend that LJ has developed a tic. Or a habit. Not sure what the right word for it is, but here it is: after a certain - variable - amount of "inactive" time, LJ will kick you out and you have to log back in again. This was not always the case, and the practice as presently coded into the website is an annoyance to me.

The suspicion exists that I am not alone in either the experience or the annoyance.

Anyone else?
