What I learned from launching on a Tuesday vs. a Thursday

I've launched twice. First time, Thursday afternoon moderate traffic, a few comments, faded by evening. Second time, Tuesday morning same product category, similar audience, but the thread stayed active for two days.

The difference wasn't the product. It was the timing and the fact that I was there replying within minutes for the first six hours. Launch day is not a broadcast it's a conversation you have to show up for.

Timing matters but presence matters more have you noticed a real difference between launch days based on when you posted or how present you were?
