Many (most?) posts in the Sequences are tagged as [Personal Blog] instead of [Frontpage]; is this deliberate?

Here are a few examples from posts that I recently had reason to consult:

Belief in Intelligence:

Aiming at the Target:

Measuring Optimization Power:

Efficient Cross-Domain Optimization:

(There are several others, these are just the posts I had reason to interact with today).

 

Perhaps they should be moved to the front page? Several posts there seem obviously fitting for front page material, and they are quite central to the LW community.
