Topic: Clean URL for Blog Site and Tags

Sorry for my bad English.

I'd like to clean up the sites URL's in the blog and the tags.

http://monstra.org/blog?page=2&tag=monstra
http://monstra.org/blog?tag=monstra

The problem is that I can now do no more facebook Share on these links. Can the URLs somehow improve in the .htaccess so that there is no longer a question mark?
Thanks 4 Help
