Now I don't mind, as what's important to me is that people read and think about what I have to say - this isn't my job. However I DO ask one thing. I don't care if you want to link to this blog and comment on posts on your own. That's part of how the blogosphere works. I also don't mind if other publications publish my blog URL and also post excerpts from it.
However if you want to repeat a post, in full, and publish it on a subscription based magazine or newspaper, ask. I know this isn't copyrighted, but it is simply polite and if you're seeking to make money from what I write I want to know.
