I don't blog, but I do use my Facebook page a bit like a blog, I publish photos, random thoughts, status updates I find amusing or interesting, and don't necessarily expect much feedback. I do consider that other people will be reading it, though, so it's not a private diary, and if I never received any feedback at all I'd probably stop.
But I really don't see any big difference between blogging, Facebook and writing here on TE. Many threads here are people posting about their day or personal experiences, big or small, either to commiserate with someone else but often just to share an experience. And that's to what many people would consider "total strangers". By comparison Facebook or blogging to a handful of known friends is an intimate chat.
Winter riding is much less about badassery and much more about bundle-uppery. - malkin
