I suggest you don't mix blogs. If you want to do FoxPro, do one on FoxPro. If you want to do sports, start a different blog on that. I've unsubscribed to several blogs because they strayed from technical to other things.
Well, I'd rather read a blog that mixes it up, as opposed to a "pure" blog that's essentially uninspiring and indistinguishable from the daily news...
