Trend spotting

When it comes to digital images I'm no purist, but if an image says "crop me, make me look old," is it OK to listen?

I know this is a TTV-inspired trend -- TTV is Through The Viewfinder of a twin lens camera, usually an old one -- but I genuinely love the look.

So do I fight the urge, or give in and just play with my images? See my Flickr feed (left) for other examples from my weaker moments.
