Jason,
Yes, Hubspot is awesome. If you haven`t already, send your site through website grader at http://grader.com. Whether you are a blog reader or not, I would definitely consider signing up for their Blog feed as well as a few others I`ll mention shortly. If you don`t currently read blogs, I personally use Google`s Reader which is a great free tool for bringing together all RSS feeds that you may be following.
A couple of other sites to take a look at would be - http://SEOBook.com and http://TheOutsourcingCompany.com
I`d recommend browsing through their sites, but for certain signing up for their RSS Feeds / Blogs. Both resources, similar to Hubspot, have there services they`d like to sell you. I personally follow both but have not paid for any service yet. Even if you don`t though, all three companies offer tons of free resources that should be able to help you out.
Regards, Michael
