For those of you coming in on the #twittermigration, it may take some time to get used to the slower pace here. I had tens of thousands of followers on the bird site. The community is smaller here, and there is no recommendation engine pushing content onto your feed.
You community here is what you make it. Take it slow. Enjoy it. Let your nervous system adapt to less stimulation. I suspect it's good for you.
It has certainly been good for me (and I used to make my living on Twitter).

Vivaldi is pushing hard on the horizontal tab scrolling, but for me the Reading List is the big seller. I don't need the horizontal tab scrolling if I have a reading list.
