Well, it isn't a law that we have to have all of us on a blog roll. More like a fun idea, I think. If I had a food blog as my primary blog I wouldn't want to cramming it up with a bunch of fun mommies because that is not your audience, does that make sense?
If you were a green person, I doubt anyone would want me on their blog roll ... I try hard but I am not a die hard. Sometimes I poke just a teeny bit at major greenies, nothing too serious.
In summary, not a law.
Read the blogs for awhile, if you don't care for the style or the tone or have no intention of ever going back to read it ... don't link to it. I won't be offended.
But if you do love me, and you will love me so much you will want to know my address so that you can send me gifts, by all means link to me first and come back every day ten times to add comments
