In general, I am happy to add good blogs to my blogroll. My main criteria are as follows:
1. I don't want to blogroll any brand new blogs. Ask for a link after you've been blogging for a month and shown a consistent history of at least daily postings. Feel free to send me an email prior to that if you'd like a link to a specific post that you consider particularly apt for my readers. You'll get more traffic from a post link than a blogroll link, anyway.
2. Don't send me an email simply requesting a "link exchange" without any indication that you've read my blog and are familiar with the topics I discuss here. I get an appalling number of these and they quickly go into the trash folder. Tell me why my readers would like your blog. Do you blog about politics, economics, finance, heroes or football? Odds are very good my readers will be interested. If you blog mostly about recipes for nesselrode pie, I doubt there's going to be an overlap.
3. I don't blogroll sites that espouse hatred or violence or racism. I prefer sites that don't use a lot of profanity although I don't require a PG rating. Obviously if you're funny, you can get away with more than if you're angry.
4. Preference is always given to bloggers who comment or link here.
5. I generally don't blogroll liberal bloggers, although that's not a hard and fast rule. I'd be happy to blogroll frequent commenter Paul, although I don't know that he wants the folks that come over from here; it's not quite the same thing as nessselrode pie, but still at cross-purposes.
6. I will usually remove a blog from the blogroll if there are no posts for over a month.
7. I reserve the right to revise/break any of the above rules.
