It says nothing about "us as a community". It is a message aimed at individuals, not the community as a whole.

If 1 person out of 100 go hulk-rage-smash because of a crash, then that does not reflect anything on us as a community.

Besides, such a message is fairly standard in beta nowadays.

I think it's because of what they've seen with betas from other companies.  Have you ever spent any time in the Blizzard beta forums?  It's a jungle.  People think they're playing the final release.

I just felt it was odd that SD felt the need to add qualifying language. It's blatantly obvious that we're playing a beta.

This is really the only game forum I visit, so I guess I wasn't thinking about the type of people Darxim and Heavenfall mentioned above.
