Seperate permissions per category?

[Kohhal]

Would be great if individual categories could have their own permissions, set by the user. So they can have different areas of their blog available to different people depending on how public they want it to be...

Yes, I am testing the Blog now and 'hidden' categories, only available to the Webmaster and Moderators would indeed come in very handy for me now.

Everybody should have this possibility, not just the mods. After all, differently from a thread in a forum, a blog should truly be in the hands of the blogger. So, outside of any illegal postings, the users should really have control over who gets to read what.
I personally would love to be able to set up some more personal entries, available only to the people on my buddy list. This is really one of the biggies that are missing so far.
