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.
For a forum visitor, does seeing powered by vBulletin strike a softer note than seeing powered by phpBB? Not because of features - but simply because vB is commercial software?
In other words, if a community had the same content, would a visitor think of the forum as more serious / reputable / better simply because of the software used?
Just throwing this idea up in the air people. Interested in hearing responses.
