That's an interesting question.
I think that Jeff Atwood does have a vision. Whether that vision and mine have something in common is yet to see :lol:
The software has great potential. If that potential leads somewhere is yet to be known. As per today, it is not very intuitive for me (but maybe because it is kind of SO-ish and I rarely visit SO, only when my Google search drives me there and I may not as familiar with how things work there)
I does have some features that I like such as posting youtube videos. I can simply copy the youtube url and the paste in my post and that's it. Those are silly things but that make a bit of difference. It is not that it is very hard to do in a classic forum like this one but every little helps.
In the same way, there a little things that I find hard to find, if I find them at all... and that also annoys me.
But I think is good that someone brings a fresh approach to the same problem (venture or not). If he is able to listen to feedback, his product can be even revolutionary.
