I tend to agree that extremely long mega topics start to be absurd. How do you search them? Who actually reads them? We have a 10,000 reply limit for performance reasons (it is a long story, but a list of all ID numbers in a topic is sent down to the client) but I am begining to think that default limit makes sense across the board even if we resolved the underlying performance issue.
It’s generally helpful to have some sense of time scope in a topic title anyway, as previously discussed
