[wp-hackers] wp_head()

[Erick Hitter]

*Init*, as Chris mentioned, is the first hook WordPress fires, but there are
many things that can't be accessed that early. In particular, the
conditional tags (is_home(), etc) aren't populated at that point. If you
need to hook early but also want access to the conditionals, the *wp* hook
is a better choice. Really, it's a matter of what you're trying to do and
how much information you need, so be sure to experiment with both to see
what information you have access to at what point.
