There are always times when there are less posts being put up. At other times it seems really busy, because some controversial or popular topic came to the surface.
Also, it's always like this at this time of the year. Just watch the news, and you'll see items that would not even get a mention during other parts of the year. We Dutch call this cucumber time, because A) the cucumber crops are coming in, and B) because of the lack of proper news, you see items such as the all important 'Farmer Johnson has grown a world record size cucumber'....... Yawn......
