Thank you for 'pestering' me John.
As you said, an interesting experience, one which also left me pondering on the omission of a hashtag. How did its absence change the experience? More meandering? Relaxed? Sure. Or haphazard? Maybe.

I'm minded to reflect on the bi-directional nature. First there's the (intended) audience for the photos you share, which will be the 8 people mentioned in the 7 tweets. Then there's the unknown audience of the invitees of your invitees. And of course, the wider population of your followers. In the other direction, you *become* the audience for the photos of invitees. Each little photo has a story behind it, which of course you never know because ... 'no explanations!' I found each of those little prods to the imagination appealing.
