I see that Seth has similarly gained and waned within a few hours as I am expecting.
When I submitted my first list back in 2011, there were few enough people participating (ten) that my meagre total was within the top ten. That soon changed as more people got involved, but most have managed to grow theirs substantially in that time. With a full time job and responsibilities, coupled with bouts of apathy and other buggerations, my list-building efforts were always going to be slow. Of course it doesn't matter a jot. The listing side of things is a bit of a light-hearted aside to generating a few records and stimulating the mind.
