I don't mind the killing off of stuff that doesn't catches on it's a mark of dynamism.
When Google Reader died, it reminded me not to become dependent on other peoples' computers. I had gotten lazy and was attracted to a well done tool, and it dying was a helpful reminder that I'd been suckered, and was lucky it wasn't something more important.
I've been better at not making that mistake since.
Most people are conservative like you. Your sheer numbers are why crossing the chasm is so important for the long-term survival of a new offering.
I love discovering and trying out innovative new products, and have made it a large part of what I do professionally.
However, some offerings I take more seriously than others.
With Google, if it's not search, data or ad related (i.e. the stuff that makes them money), it's generally the case it's not going to be around long-term.
