For a lot of communities that deals with a lot of interactions, the probability of a first user joining the community is mostly based on his/her first impression of the community.
If the user sees a lot of threads with 0 Reply appearing in thread list, user might get discouraged from joining community as he/she might feel that the community is not interactive enough.
Will it be better if we did not show zero replies?
Say if there is not yet a reply on thread do not show the number of replies. (0 replies) in lists
Else show the number of replies
What do you think?
