After awhile you just lose interest in something. Its human nature. Over time I've seen many people come and go and only few remain constant. I'm sure there will be a day I stop being a constant, although I have taken 3(?) several month vacations myself.
That said I have written before there are two types:
A: Those who come back and checkup now and then
B: Those who never return
Blokker is certainly a type A and he is still very much with us. Although he is not very active he still helps pay for costs for website & server to my knowledge. He is very busy maintaining the Belgian railroads!
