1. The act of blogging for the self (i.e. a personal blog), not for income.
2. The act of blogging for the masses, but not specifically for the income potential of the entries (i.e. interesting, thoughtful entries that are not specifically written to draw higher-paying advertisements and cost-per-click rates).
1. I like Jim's blog. He's a great grass roots blogger.
2. Did you see Maddox's blog? He's interesting and entertaining... really grass roots.
