I think one thing to keep in mind is not all of us are full time traders, many are balancing work and busy lives with trading so don't always have time to read every announcement before the market opens.
If some posters give a heads up in the pre-market thread then that's gold and is what makes DT a great thread and I think many others agree.
Giard is the best tipster on the thread bar none and his input is worth it's weight in gold, I think just many disagree with his opinion in this instance.
