It would be good to have "ice breaking sessions" aka kopi sessions where people meet without godzilla lenses or gears, but to know one another and build friendship first. That way, the problem with "paiseh to take out my PS when the one next to me is pulling out a 300m prime"... it should end up as the PS guy and the godzilla lens guy exchanging tech tips and maybe have a healthy discussion to why each platform has its plus and minus.
But more importantly, this is about community, and building a community should be priority over a peacock exhibition of who has the bigger and better and more expsive gears, which I believe is never the case with most members here. I have some friends in here whom I have known for years and though they own Godzilla lenses while I was on a prosumer, that never stopped us from discussing photography at all. In fact, we have all become very good friends over the years.
Community first. Has to be this way, I believe this is what CS set out to be in the first place. Having pros/seasoned shooters among the community is a bonus because then the newbies can start learning from them.
