Good points on the research done mentioned there! That is also real good publicity. You can't buy that kind of publicity, coming from a customer who looked at many different platforms.

As to iHang on mobile, I use the browser and find the only thing there seems not to be a way to do is edit a post. That's no big deal other than I tend to find I make some typo that I don't see until after I press submit, but that's my fault. Otherwise as far as I can tell everything can be done in the browser on a mobile device. Now I will admit to only trying the mobile app briefly and concluding I'd stick to the browser, so I don't know all that can be done in there.
