When deciding what forums to join? Because while a lot of articles say how little the choice of forum software matters in terms of activity, I think that's actually rater inaccurate. It does matter. I have heard people say they joined the forum because they liked the software used (back in the olden days, I actually had people say they joined a site I was running because I used vBulletin). And I think it goes further than that. Look at a recent topic in the phpBB section here where someone clearly said they think phpBB correlates to 'newbie/start up forum'. How many people might have that attitude then take it further and decide not to join a phpBB or free software using forum because they're not certain the admin is going to stick with it or the forum stay around for long? How many others might join a forum if its the same script used as on other forums in the same niche? At some point, familiarity might mean that potential members have expectations of forum software that need to be met for them to join. Maybe because it's easier to join a forum using a script they know how to use than one they don't, similar to why many people use a QWERTY keyboard despite it not being the 'best' option. That's not even considering all the people who join your forums because they see a link to them in your signature on the official support forum. I used to have vBulletin.com and vBulletin.org members with an interest in the topic join as well based on my signature on those sites. Probably get others when I posted on Invision's support forums or what not. Do you think potential members take the forum software used into account when deciding whether to join a forum or not?
