I have been wrestling with this issue for over a year: why blog?
This blog post from a marketing consulting firm is the best I have seen out there that explains why this is important for CEOs and thought leaders everywhere. Here they say you need to blog a few times a week. Not sure I buy it 100%, as I try to post something intelligent about once a month, if that. I am not sure anyone has really that much to say every week that's worthwhile. So for the moment, I am going to try to stick to only posting stuff I think is "uncommon" knowledge, so that when I do post folks will find it relevant. I, and my readers, can't spare the time for anything else. What do you think?
