Yesterday Google and now Microsoft both announcing their own chat bot integration and yet there is not a single link where I can try out either one of them. What is this new trend of announcing things as if it's available for general use and then hiding it behind invites or not making it available at all.
If they were worried about getting a bad start with the general public or scaling concerns they could have easily put it somewhere that only enthusiasts (e.g. HN) would find it. But no, instead...announcement and nothing usable.
Call me back when I can try this, Bing.
