Off the bat Knol, Google code, Orkut, the end points changing
for many of their APIs and monetizing so many of them, their
everything email replacement (I forgot what it was called - it
was cool though) .. Google reader ., that's a few off the bat
though. A lot of them directly affected my processes but it left
a taste of "not dependable" over the years. I still like them -
been using regularly since 2002 when they acquired Usenets
archives - that's another one - they made searching by date
impossible and removed Boolean). Moving photos around is another
one. I can go on but this is a start. I have a long internet
memory and I'm less impressed by novel things if they're just
one off experiments and don't stick around.
