too open...?

I have to admit, I don't post as much as I used to because I'm always concerned with who is actually reading my posts. On the flip side, I don't necessarily want to lock out everyone out of my blog for the slight chance that it might actually be useful for someone, or for networking purposes. I suppose what I need to keep in mind is that I should not confuse a blog for a journal - definitely keep those two separate! ...speaking of which, time to go #2.
