I once described blogging as being a bit like lobbing pebbles into ponds. Each blog post causes ripples, however modest, to go out into the world, hopefully causing ideas and opinions to change. Over time you get better at lobbing bigger pebbles into better ponds.
I love watching my daughter Mollie lobbing her blog posts out into the world and causing ripples. Her most recent post on the #metoo theme nailed some of the core issues and has triggered many interesting and thoughtful reactions.
This is how the world changes. Lots of pebbles, lots of ripples, bigger waves.
