Some Mastodon tips for someone with ONE DAY'S EXPERIENCE. Turn on the Advanced Web Interface - it's like tweetdeck. Make Columns. Verify yourself with links in your sites and rel="me". Consider your sounds/notifications for sanity. Go to https://fedifinder.glitch.me or https://twitodon.com and get an export of who you follow on twitter and import it here to follow the same folks. Turn off sounds. Note that Bridges exist to Twitter for your favs.

Fediverse accounts of your X/Twitter followings

@shanselman Great tip exporting/importing followed Twitter accounts. Used twitodon.com few minutes ago. Sadly only 3 Twitter accounts were found from my followed list at the moment 😕. Let‘s see what the future will bring. 👍
