I follow a bunch of developers (surprise surprise) and read mostly technical blogs, I've found a lot of developers mix writing blog posts about their personal and family life alongside technical posts. As I've been reading I've found those are some of my favourite posts, as someone who balancing professional and open source development with parenting, I really love hearing about other people's experiences doing the same. It's not a side that I read much about elsewhere outside of personal blogs.
That's a long way of me saying, keep on blogging strangers, someone might be reading!
