I definitely agree with the conclusion that one of the answers to information overload is to trust that other people will read things which I won't, and that I'll find things through them or through the people who read them.
I think it's also important to be open to the possibility that some things will inevitably slip through the cracks from time to time. This would happen even if you spent every waking hour, as well as the hours when you should be sleeping, trying to not to miss anything. This isn't a tragedy. I think it is an old-fashioned and almost arrogant mindset which causes people to think that they can stay on top of everything which happens in every important topic. The reassurance which these people crave will only guarantee further stress and anxiety.
Information overload used to be one of my pet topics. I've noticed this since I've been looking for posts to add to my new memories section.
This is the list on my sidebar which includes some of my memorable entries. I've biased my selection towards older entries, especially from this blog's Radio Userland days. I can find more recent posts using TypePad's search blog feature, which obviously doesn't apply to the Userland posts. That's what this list is really about - making it easier for me to feel connected to the previous incarnations of this blog. I sometimes like to re-read my older posts and ask myself, do I still think that now? Would I write that now?
At the moment, this memories list has the prominent real estate in the top right corner, but after a few weeks I'll move it towards the bottom of that sidebar.
