It just took me three tries to answer this question. The first two, my answer was automatically converted into a comment. While I appreciate what this feature is trying to do, it was really aggravating. I felt like I had to jump through hoops just to post an answer, and maybe even worse, the site involuntarily made me do something I knew was bad. My first two tries:
April Fools joke. See [What is "chat with an expert"?] on meta.SO. : [link url]
It's an April Fools joke from the site. See [What is "chat with an expert"?] on meta.SO. : [link url]
My absolute biggest complaint is that it's converted to a comment immediately, without any chance to edit it. I then have to copy and paste it back, fix the markup a little, delete my comment, and try again.
To make a specific feature request, I think the nicest thing would be to give me the choice: convert to comment ("this looks trivial, want to post it as a comment?") or don't post ("write a better answer"). Failing that, you could just refuse to let me post the answer, keeping the cooldown period, with an explanation.
If you think these will encourage people gaming the system - instead of letting it just stay as a comment, lengthening an answer until it gets through - you could keep the old behavior for low-rep users. (Or I suppose you could have Community flag answers as low quality if they were submitted like this; I can't imagine it's so high-volume that it'd clog the flag queue.)
Again, I understand encouraging real answers. But I was trying to write one, and the effect of this mechanism was to make that harder and discourage me, the exact opposite of the goal.
Edit/bump: I just ran into this again, and given that the site also enforces a 60 second cooldown on trying to answer again, I deem this a bug. I have a ton of reputation, full privileges, I'm a mod, and I have to wait 60 seconds to fix up my too-short answer. Feel free to block me from submitting (as with "Body must be at least 30 characters"), but don't lock me out for 60 seconds.
