Calm down, it's only a talking shop and much of what you regard as crap, may be someone defending a long held belief, while another's enthusiasm, or newly discovered product / device / market, might get them carried away, for a while.
Remember, some people have seen most of the ' new inovtions ' before, maybe in a different format, or even wearing a different name.
The problem, is often that a convert or dedicated user sometimes overenthuses, and another who has taken a completely different road feels the need to re-dress the balance. It's normal realtime life
Because we are invisible and there is no tangebility we can only use words and in my case type them very slowly.
