Our survey is now up and everyone is invited to vote! 
Thank you for taking your time and creating this survey, 1miau! I already made my vote.
Needless to say, those which will vote to keep "Comments" column must also vote against having comments "hover" format and vice-versa (I hope there will not be contradictory votes).
We also need to specify how long our poll will be running.
I believe that 14 days are more than enough for having a good image of what voters want to see changed / kept in the table from OP.
Once again, great job!
