It is probably not appropriate to share every small detail of your offline life (boundaries are important) I find that readers respond very well to the occasional mention of the things you’re doing outside your blog.
I generally only mention these types of things in passing or use them of illustrations of a point I’m trying to make (example) but am constantly amazed by the numbers of comments and emails that I get when I do from readers who have had similar experiences or from readers at a similar life stage.
For example – simply posting that I’d become a Dad has had a significant impact upon the interactions that I’ve had with many readers. The day I did a whole new type of reader (mainly blogging dads) seemed to appear almost over night (I suspect most were already readers but somehow in sharing part of my journey they stopped lurking and made themselves known. In response to me sharing something more they too began to share more (both personally but also on the topics I was writing about).
While I’m sure I’d get complaints if I shared this type of thing in every post – the occasional (and appropriate) glimpse into your life can somehow add to your credibility, relatability and trust as a blogger.
How much of your real life do you share on your blog?
