Another non-sharer! Brilliant! I'm not too terribly keen on sharing intensely personal details of myself on these things, either. So there's nothing wrong with being unwilling to over-share. I haven't figured out what to do with any blogger social media things, myself. I mean, if I wanted to be truly obnoxious, I suppose I could post my to do lists.
Though I'm pretty sure that would make everyone gouge their eyes out.
