So X has done it. After years of algorithmically force-feeding you content you didn't ask for, Elon Musk's favourite social experiment has finally added the ability to sort your timeline by topic. Custom timelines. A feature that lets you curate what you actually see, organised around the subjects you care about.

Cool! Great! Wonderful! Also - and we cannot stress this enough - this is literally just TweetDeck.

A brief, painful moment of silence

For those who weren't chronically online during Twitter's golden era, TweetDeck was a power-user's paradise. Multiple columns, real-time feeds, topic filters, list management - it was the cockpit of the internet. Journalists lived there. Developers lived there. People who used the word 'timeline' as a verb lived there.

Then X acquired it, locked it behind a premium paywall, gutted its best features, rebranded it as 'XPro', and sent it off to die quietly while everyone pretended not to notice.

And now, according to Mashable, X is rolling out custom timelines - a way to organise your feed by topic - like it's some kind of innovation. Like they didn't take the neighbourhood library, burn it down, and then open a bookshop selling some of the same titles at a markup.

Okay but does it actually work?

Here's the thing - begrudgingly, yes, this is a useful feature. The ability to filter your feed around specific topics rather than just drowning in the algorithm's best guess at what will make you angriest is genuinely valuable. If you're a sports fan, a tech nerd, or someone who exclusively wants to see pictures of dogs, having a dedicated lane for that is not nothing.

The question is whether X can execute it without immediately locking it behind a subscription tier or breaking it in a software update three weeks from now. Recent history suggests... tempered optimism, let's call it.

The grief is valid, but so is moving on

Look, TweetDeck mourners - and there are many of us, staring wistfully at Wayback Machine screenshots - are allowed to feel a certain way about this. It stings a little. It's like your ex returning your favourite jacket but only after they've worn it out and stretched the collar.

But if custom timelines genuinely work the way the platform suggests, and if they're accessible without requiring a premium subscription, then maybe - maybe - we give it a shot. Not because X deserves the goodwill, but because a usable timeline is a usable timeline.

TweetDeck is still gone, though. We're not forgiving that.
