I'm happy to make all of my original content, unless otherwise noted, available under a Creative Commons Attribution-Noncommercial-Share Alike license.
This license permits you to copy, share and transmit my work free of charge, in any medium, as long as you credit me (Cal Harding (a link to the site would be nice, too (nested parentheses!))). You're also allowed to adapt or build upon my work (like in mash-ups or whatever) as long as you credit me and distribute the derivative work under the same copyright terms. If you want to do any of these things for commercial purposes, you'll have to ask permission first (see below). None of this affects your right to fair dealing or fair use, whatever you want to call it. Keep in mind that these terms extend to the use of my RSS feed.
All of this ensures that the work remains "free" for anybody to use without breaking the law - unwittingly or otherwise - or being hindered from sharing by the threat of litigation.
Note: This does not include the right to republish any images from the site, for which I may not be the copyright holder, nor - obviously - the content of any ads, nor external sites to which I link.
Commercial use: If you want to use any of my content for commercial purposes, or for any reason want to be exempt from these licensing terms, just drop me a mail at cal{at}calharding<dot>net. Don't be scared, I'm not uptight about this sort of thing and will probably say yes; I don't mind commercial use, but I'd like to keep track of it.
Comments: User comments remain the property of the poster and I accept no liability for their content, though I do reserve the right to make fun of them.
Twitter: In case you're wondering, all of my Twitter tweets (I hate having to use this stupid terminology) are public domain, so do what you want with them.
Disclaimer: This page serves as a simple explanation of your right to use my work (along with a bit of self-righteous proselytizing), but isn't a legal document or anything. If any wording on this page is in conflict with the terms of the Creative Commons license, the license takes precedence.
Final Thought: If you don't know about Creative Commons, I encourage you to read up on it and consider making your own creative works available under such a license. This allows culture to evolve and creativity to flourish unencumbered by ridiculous and outdated copyright laws.
