I’ve never used TweetDeck but there is the Control Panel for Twitter, which makes it usable. It can auto-block all the bluechecks with under a million followers, hide the “For You” tab, block ads, and restore the old Twitter branding.
Unfortunately the main reason I use Twitter is not the platform itself, but the public figures that are on it. Mastodon (mostly) doesn’t have that, though there is a trickle of some coming over.
That’s not how our parliament works. The amount of people calling for an end to the speaker’s independence is concerning.
The speaker’s job is to uphold decorum of parliament. This one spectacularly failed to do that, and resigned as he should. That doesn’t mean we should make it a partisan position.
