I posted there 3 comments and got 6 downvotes which resulted in extreme negative emotions all the evening that day. While I understand why they were downvoted, my emotional reaction is still a surprise for me.
Because of this, I am not interested to participate in the new site, but I like current LW where downvoting is turned off.
It may be worth noting that "6 downvotes" need not mean that 6 people downvoted you. LW2 has "weighted voting" which means that the number of points your upvotes/downvotes change the victim's karma by depends on your own karma level. So maybe you were downvoted twice by weight-3 users, or three times by weight-2 users; in any case, losing 6 points probably corresponds to <6 downvotes.
What are your first impressions of the public beta?
