Oh totally, hon, no one will disagree that engaging with your watchers/following isn't good or you shouldn't do it (quite the contrary) or even making contacts and friends with other artists is bad (nope, that's awesome). However, if the people running the site aren't doing their part than it becomes a sinking ship of a site.
You're right that the staff can't change the community attitude or opinion, however, they can change themselves as well (like you've been saying about artists starting with themselves, the staff need to try that bit of advice too). And their change is just doing their job by enforcing site rules, discourage art thief, providing better customer service, and having more site mods.
"Start with yourself" to see the change is the world is excellent advice, however, DA needs to meet us halfway there. It's not the community's job to police each other on art thief or following rules, nor do we have power to enforce anything like that. It's also not within the community's power to provide customer service if upgrading to CORE fails and a person needs help. (this is how I see DA as a broken site)
However, I'm glad you're still enjoying DA and are happy there. That's awesome, enjoy is as long as you can.
For some of us, DA isn't the only publishing site out there, friends can be followed on other social sites, and it makes sense that some have decided to post else where. That doesn't make them bad community members, it just means DA isn't for them.
Honestly, a thread about DA and its problems makes more sense to have on the DA forum, instead of here where we're all happily existing is our peacefully nice community.
