Cache is not utilized as much as it should be

[nathan-osman]

Although the query optimizations I performed have decreased page load times by a lot, the cache is still grossly underutilized. My goal is that the content blocks of nearly all non-form pages would be cached. This leaves a few interesting considerations:

• relative dates (ie. "2 minutes ago") will need to be calculated in JavaScript
• there needs to be a correct way to invalidate the cache whenever content changes (this is the tricky part)

I envision that this will end up being an ongoing process.
