Years ago, one of my mentors preached the importance of being adaptive and adoptive. By that he meant (or at least this is my take),
a. don’t be so caught up in yourself that your unable to change your ways. Things are going to change quickly, and you need to deal with it.
b. don’t be afraid to take action when you see something that’s good… from someone whom you trust and/or respect… and add it to your repertoire. They’ve likely spent a lot of the time that you’re about to spend thinking about it.. sweating over it… losing sleep over it… and just plain wasting time on it before you get it done.
Now, the important part of part B here is that you choose wisely. Don’t go willy-nilly adopting things from knuckleheads… (or more likely those who have not thought them through).
So when you see something that inspires you (like the WordPress Quick post form), use it.
