When is the best time to blog?

Having co-workers that do public relations, they seem to have timing down. They know when to put out press releases for the most coverage, when the best time to call people is and what time is optimal to send out an email campaign to get the most responses. So that got me wondering, when is the best time to blog?

Being an avid blog reader, I’d have to say that it doesn’t matter to me when someone posts a story, I’ll get to it eventually. I tend to read feeds in the morning and early evening, but that doesn’t mean that I skip any or don’t put enough attention towards those that post at 1am compared to those that post at 8am. For me, I don’t think there is an optimal post time for someone else to catch my eye. But there may be for social sites as there are probably less incoming posts to Technorati or Digg later in the evening. This may give your post a little added exposure due to less competition.

What do you think? Do you think that there is an optimal time to blog? Some sort of golden window for readers or for social sites? Or doesn’t it really matter?
