Partly the theme, and partly just a busy time of year. The last two themes didn't do much for me. It was almost as if only flowery images were the theme. The themes were too restrictive. If I would change anything, there would be no holiday themes. Post all that in the regular gallery. It's like looking at the calendar and knowing what the next theme is going to be. Too predictable. It's also spring time, bordering on very nice weather. It's only natural to be in front of your computer more when the weather outside stinks. Now that the first taste of summer is hitting, everybody wants to venture more.
