I can't say much for outside of Cairns, but the scene sure has died here over the last 10 years. Less public outings, less events, less support. The reason for that is anyone's guess.
With regards to the forum? Too many ideas and not enough action. Not having a go at the previous posters as it is obvious you're keen to see the place thrive which is excellent, but why doesn't someone organise a cruise? Why doesn't someone post a topic EFILive? What doesn't someone post a topic on cool photos of the day/week/month, whatever? There have been these topics for years, but I wonder why people don't post their ideas in a new thread rather than reply with an idea? You guys are the life of QSS. It is what you make it. The more people contribute the more others can have their input on and the community thrives. If I can do something to stir up more interest I would. I often post videos or auto related news, or whatever, but often get few or no replies.
If certain people seem to contribute a lot they can be promoter to moderators of the desired section to run and maintain it. It would be good to see someone contribute and encourage others to get in on a section.
Hosting aside, I've spent a substantial amount of money on this community over previous years. I think its prime was in around 2008-2009 but seems people are losing interest, or whatever. Either way it has been 5 years since the forum was opened. Traffic wise it hasn't really changed in 2-3 years. It hasn't gone backwards, but still there is less contributions than there used to be.
There is hundreds, if not thousands, of car nuts on here but few have much to say. The potential for an awesome community of car enthusiasts is there, but not being harnessed. Blame whatever you like, but ultimately, the members make the forum. I just put the tool there for people to use. It's up to the scene to support or neglect it.
If people have ideas they think would contribute to the forum I am happy to spend the time/money on it.
