I've attempted to show my website to my family a couple of times, but I'm a techy in a generally non-techy family, so they're not particularly interested. I mostly use it to talk about things I've done and I have referred back to it on a couple of occasions when I know I've solved a problem before and want to see how I did it at the time.

I attach it to my CV so I keep it professional enough for someone else to look at that I would want to impress, but still pretty casual because I try to write like I'm explaining it to a friend, someone who knows basic programming stuff but is a novice to the actual topic of the article
