Blog link nuisance(s)

Blogs are supposed to be the reflection of the blogger. Its mine and only mine, my personal space. What I write is what I think and believe in. Then who do I invite? Who do I keep in my links? Should the blogroll reflect changes in my own thought process? Some of the nuisance are:

1. Damn! my manager blogs too. Now I have to link him on my page.
2. I don't know how to delete this person's link. I never liked him but I linked him once and now he's there.
3. His contents rarely change. Shall I remove him?
4. By linking him will I maintain my network?
5. He blogs about things I don't believe in.
