I think this is how I'd feel if I was an old member here. Unfortunately I'm new, so I'm a bit conflicted. I think if there are changes, they'll be minimal. There are only three ways that new members can handle the next few days. 1) The people who don't work here will go back to Reddit, as I'm sure a lot of people already have. 2) Those who try to force themselves will be ostracized by the existing community, like the user, ahametals, that you mentioned. 3) The people who mesh will integrate and provide more quality content after they learn the ropes. The first two will settle, but it seems like you're most concerned about the last part of the third option: "after they learn the ropes". It's always difficult learning new things, and communities are so much more intricate. It's going to be a bit rough for newer members like me who really enjoy the community but are afraid to participate because they might be a nuisance. But if we're staying, we'll get it. We'll have to or there will be no reason to stay. So that's how people work. I respect your opinion, and I'd have the same if I were you. This situation really isn't all that bad for hubski though, so I hope you'll see things settle down after a few more days.
It's ok to be afraid of being a nuisance. It can be pretty helpful to have that kind of mentality. At least it is when you're joining a new community. It helps you pay attention to how people act and what they expect. It helps you learn how you can actually benefit the community instead of just adding to the noise.
