The first thing I noticed with Twitter.com’s redesign is that the algorithmic timeline (aka top Tweets) is set as the default.
A few days ago I wasted some time looking to change this setting in the More > Settings and privacy page. I couldn’t find it there. I then googled, but still couldn’t find the answer.
I googled again today and found the solution in this Mashable post.
The timeline preference setting is moved from Settings > Account > Content to the centre-right of the home page.
The bright side is that at least now it is easier to change the preference if Twitter zealously overrides it, as it does from time to time, like on the mobile app.
