Include keywords in important places. Include them in your blog post title, the large "headers" introducing a new section, the first few sentences of your post, and in links. Change your settings so each blog post's URL includes the title of the post, not the date it was posted. Try to make these as descriptive as possible to raise your ranking in search results and attract the right audience.
I will quibble on one point though, your comment about BBT getting 13,000 subscribers before launching even though you “had nothing but a coming soon page and an invitation to join our email list.” As I recall, you also had a freakin’ awesome video on that page as well that just made people yearn to give you their email address, even without knowing a thing about BBT. So that didn’t hurt, either. ; )
Make it easy for readers to browse – If you want more pageviews, you should make it as easy as possible for readers to read your other blog posts. You will want to make it easy for readers to find your blog homepage, categories, tags, search bar, and so on. Also, I recommend including links in every single one of your blog posts, so readers can easily find related topics.
