I'm an old-timer and I haven't actually used Pinboard in years. I'm curious how others are finding it useful in an era of synced browsers and saved tab groups etc. If there is any utility at all, the paid plan is a steal.
1) I take links from there and automatically share them elsewhere. I've got about 2,500 who read them in various places (Twitter/Facebook/Dreamwidth/Livejournal)
2) It's invaluable when I find something debunking the latest nonsense, and can easily find it again 5 years later when the same nonsense resurfaces.
