Every blog starts at post #1... and then either dies a slow horrible lonely death, or is updated occasionally/whenever you think about it, or becomes a thought provoking tour de force.
The litmus test of whether anything I have to say (or type, as it were) is important, relevant, sane, or useful, is up to you.
Unlike the Marines, I have left a blog behind. It served it's purpose and then was promptly abandoned by me. Like digital trash. 0110001010000111100100100111101001010101010 littering at least one server somewhere. Litter sucks...
