And on and on it goes. It seems multiple 1000's of man-hours of work happens in the tech world, only to get dismissed and dumped in favour of $new_exciting_thing, and it's getting annoying and disappointing.
It seems to be a case of rather than iterating on something, someone else comes up with $new_thing and that becomes the fashion du jour for a period of time - lots of people quickly jump ship to the new thing - until /that/ stuff gets dumped in favour of $some_new_new_thing. Repeat ad-nauseum.
I'm undecided on whether that's a bad thing or not - but the pace of the change(s) is what I'm finding more Annoy than Shock.
