When I've been away it seems to take a few days before readers return. Perhaps they assume I've died and am never returning!
Anyway, don't panic I am still here and intend to be around for a good few years to come. If the blog disappears for a week or so, I am probably unable to access my blog as I am away or the internet is down.
The longest "outage" was when I was in hospital for 3.5 months 3 years ago.
