As said above, you are off to a good start, and it looks like you had a Web Plan and stuck to it! Good for you!

You have a lot of information to share, and part of the expertise you can demonstrate to visitors is in preparing it especially for them, not only to find real relevance and meaning, but in finding the information to be a participant in your website, either from being enabled or by conversion (teach or sell, you have to interact with a web, right?): shorter, more focused Content pages communicate more, and offer a more direct navigation for visitors to utilize as well.

Also....(more obvious and glaring)....none of the terms you are using the Copyright symbol for are in fact copyrighted nor applied for at the US Patent and Trademark Office as a registered trademark, by you or anyone else: "Organize As If" ; "It's The Filing, Stupid" , so not using the Registered Trademark symbol (®) was a good thing....
Using the Copyright Symbol (©) in such awkward manner, however, offers no protection under the law, nor indicates anything other than something of a less-than-professional understanding of real business, and it appears that this is a blunder you should not perpetuate (if your intended market is in fact Business), right?

Even though it may appear to "cover" your written expression or work, it is a bit more than convention would normally expect to see used, but in your Menu buttons also? Very tacky, IMO. Should have kept that for use on the headers, banners, titles, and other proper places.
