Never signed up for Twitter or FB. If there’s something of value on either one, I assume a link to it will be on FR.
To anyone who wonders, if there is anything on X that is important, I'm sure folks here will create a post on it. And that's one of things about X that was frustrating. There are so many posts to sift through, and if you're not following a particular person who may never find it. So as MayflowerMadam says, if there is something there that is important I'll find it here on FR.
