A month or two back, I spent some time to determine on whose LJs I could comment, and whose not. I intended to post about that, but rather obviously have failed to do so. So, a simple summary:
Location: All FAILing LJs are in Sonoma County, California. Yes, including mine.
Theme: I tried other themes. They all failed.
Account type seemed irrelevant. There was only one "plus" account, but it was in Sonoma County.
