Links! with punctuation?

Ok, here's a basic SEO question that continues to elude me.

Would a keyword be more or less effective if it was hyperlinked with the punctuation with in it?

Examples:

<a href="http://example.com>Keyword!</a>
OR
<a href="http://example.com>Keyword?</a>

Code (markup):

My experience says there really isn't much of a difference. But the optimizer in me wants to question.

 

A keyword would not be more effective with punctuation. The engines simply ignore punctuation.

Google ignores all the special characters...so not much effect..

 

Ya the special characters dont do anything. Same anchor is used, pun is cut otu
