Do you think that the forum software that's used makes a difference for a community? Suppose, for example, forum software all has the same options available. And we're talking about the same community of people.
I think its the features of a forum, as well as the community that keep people comming back, and attract new people.
The community is essential to a successful forum.
You say that if they all have the same features -> in this case I wouldn't care at all, as long as the board offered something that I was interested in, either asking or answering.
Occasionally I chance upon a site, and I simply don't like the board, and its usually the lack of features that sends me back to the google to search, so that I can select the next result in the list.
Boards that use VB and phpBB are great, I think I prefer the VB boards.
I use a different board on my site called newbb ( a xoops port of phpbb) its nice and easy to work with, but it isn't a shade on VB.
