OK - I'm fairly tech-savvy, or I should be being a programmer for a living.

But, there's something I really don't understand at the moment.

Obviously I've been busy this past week with 5 gigs in 5 days, and there's been various posts on the Book of Faces each time plus an end of gig report as I always do. Normally, my post reach averages between 100-150 people, sometimes a few more but never anything spectacular (one of next year's todo list items is to to use social media a bit more to my advantage).

However, I put a post up in the early hours of Saturday morning (a gig report) with an iPhoto (is that what it's called? ) montage of half a dozen pics. My post reach for this one post (and it's only this one post) is now nearly 8,000! Subsequent posts are back down to the normal averages.

So, any social media experts on here got any idea why this has happened on just this one post?

I've done these ones before and it's made no difference whatsoever. I'm assuming the 8k reach means it's potentially appeared in 8,000 people's news feeds (I've only got 122 followers).
