Seasons with Christmas calendar daily levels is unique- makes sense to compete in a single level for a day. Those levels have most strategy post, too. But if talk and leaderboar opens after you have done with the level already, there is no point to come here next day.
We all know when level opens. Rovio tells it inside the game. Manually opening slot for high score beforehand is much better for everyone (than doing it random hours late).
It is great to be first to write 3 star solution or top score strategy, but as competitive stand solution page can wait. You post videos amazingly fast. And competing without knowledge of alternative plays for half a day is just fine, maybe better … but there is great satisfaction if you are the one with winning formula (and post it first).
