Hey Ross, helping businesses figure this out is what I do for a living. :)
The answer is - it depends on what you're trying to sell and how you're trying to sell it. If you want to connect with people one-on-one and show of your insight and up-to-date knowledge blogs are great. Videos can be a useful tool for conveying information that is hard to explain in a static format.
If you tell us a bit more about your business I can give you some suggestions. There is no fool-proof answer that works for everyone.
