There were some bugs. And the email subscribe feature has not led to quite as many new readers as I had hoped. But that may be a function of which articles I selected to try it on.
I still really like it overall. At a minimum, clients, friends, and family have all commented on how cool/professional it is.
For example, I was talking to a WSJ reporter (about an unrelated topic), who asked how I had enabled the audio narration function.
It’s not perfect but I have seen increased reading time on those articles. There is a bit of a learning curve, but once you figure out the glitches, it generally seems well worth it.
