Since we've had the upgrade, with the automatic thread splitting, I keep on finding myself with increasing frequency reading old posts under the impression they are new posts, and only realising I'm doing so when the growing feeling of deja vu is crowned by reading one I wrote myself.

Not that I mind - it gives a fresh angle on things."What a load of irrelevant tosh this fella is writing - oh it's me..."

The incomparable Les Barker says the last, or possibly the first word, on the phenomenon - "Deja vu: a rhyme; it is impossible to experience deja vu for the first time."
