New Guess I was being pessimistic
Not having done the math, I didn't think it would be practical to actually keep the tuples you describe for all users for any useful length of time. Now if I'm reading you right, 6 months becomes a hard limit, and if you're away longer than that you lose your history? Seems like plenty long enough to me. I'm just surprised that you can keep tuples that long for the number of users and posts you cite without killing performance.

New Tuple space depends on holes.
If people don't reliably mark everything read, then the tuple-space will grow very large. However, I think most people keep up-to-date on that sort of thing, but yes, this sort of system can develop some pathological behavior.
