But there are no "cubits" here. Only forums, and a limited number of them in comparison. (There are - were - over 3000 forums at Cubits but I don't know how many cubits.) ATP is a much smaller ocean to fish in, being limited to gardening related topics.
Cubits were more or less hidden among so many varied topics. So jumping around randomly often brought a surprise. But it seem like the categories here will be limited, and easy enough to find on the homepage. Few surprises.
In my opinion, a Random Thread or Random Blog might make sense.
