I like the new update personally because I hate getting a lot of notifications from new opinions on the same question every day but at the same time it might increase opinion hijacking which is really annoying
We're looking into data to evaluate if that number needs to change. It could be bumped as some other people suggested.
But as we've stated before, introducing closed questions had a clear goal that was achieved. The number of opinions per question is up, the number of opinions with no questions fell 49% and the time necessary to get the first opinion is also down 29%.
