Censorship certainly makes HN better than Reddit, so no judgement there. I just don't understand the Imzy value proposition as a user.
For now though, there's a lot written here about things that make us different - https://www.imzy.com/imzy/post/weve_raised_our_series_fundin...
And in fact tipping itself has been one of the mechanisms by which Imzy's anonymity has been breached:

My own experiences with Imzy have been less than salutory. https://www.reddit.com/r/dredmorbius/comments/500ysb/the_imz...
Why would I want to do that anyway?
If someone gives a useful answer you give them "kudos", and that translates to tiny amounts of credit on their bill.
It's likely that companies might want to offload the forums to someone like Imzy.
Take a look at all the "gilded" posts on Reddit. I see dozens of them every day. People love spending a few bucks here and there to show their appreciation for good content, but all of that money goes straight to Reddit rather than the person that created or shared that content. I would much prefer the majority of my "gildings" to go to the user, rather than the site.
I believe there are Twitter bots for the same. Any bot should be generalizable to any text medium.
