I'm the type of blogger who always has posts scheduled for a week in advance. This is great, in case you're ever sick or get really busy with things, but it also limits your ability to really keep up with current events and trends. With blogging, it isn't as much of an issue, as you can always move things around. However, with other mediums like YouTube, for example it can be much more difficult to stay current if you've preplanned a lot of your content.
The Internet moves quickly and moves on quickly, so responding to a viral video or blog post weeks later doesn't pack the same punch as if you responded to it immediately. I have found preplanning a lot of my content does create this problem, however I'm so high strung when it comes to work and getting things out of the way, that there's no way I could let things sit for too long. It's just too scary for me.
If you're a blogger, how do you feel about preplanned content vs. putting up content the day before? I read about someone recently who has 200+ posts scheduled already for the year! To me, I feel like that would be a huge deterrent in staying current as all of your content would need to be evergreen.
