If when you write your themes you put lots of IF / ELSE statements in there, COMMENT THE THING IN DETAIL PLEASE.
Not only will you save many many posts here, but other people might actually be able to learn something.
(and that's only at the top!)
may look cool, it may look all complex and l33t but it does very little when someone wants to add something simple and either can't get it to appear or they detonate their blog trying to get it to work.
Make it clear. Please.
Don't 're-load' themes, 'comment-load' them.
