Social Media Roundup: Don't get your algorithms in a twist (12th September 2025)

It’s been another busy fortnight in the social media world! Here’s the run down of the biggest updates you might have missed:

X (formerly Twitter) Updates

  • Community Notes Expansion: X’s fact-checking style feature is being rolled out more widely, with alerts now sent to users who have interacted with posts that are later corrected.

  • Algorithm Testing: Reports suggest further tweaks are in trial to reduce the dominance of political posts in For You feeds, shifting focus back toward entertainment and real-time events.

TikTok Updates

  • New Community Guidelines: From 13 September, stricter rules apply for branded and commercial content, requiring clearer disclosures and more accountability during livestreams.

  • Trust & Safety Cuts: TikTok is reducing hundreds of moderator roles across the UK, South Asia and Southeast Asia, increasing reliance on automation and AI for content moderation.

  • Messaging Features: TikTok has introduced audio messaging and the ability to send audio or video attachments in DMs.

Instagram Updates

  • Hashtag Reach Reduced: Instagram confirmed hashtags no longer drive reach in the way they once did. Keywords, alt text, location tags and engagement now carry more weight.

  • Multi-Part Reel Linking: Creators can now link together Reels in a sequence, making it easier for followers to watch part 1, 2 and beyond in order.

  • Profile Sharing Shift: Instagram is pushing users to share more via private messages and close circles, reflecting a broader trend across platforms.

Threads Updates

  • Analytics Enhancements: Threads is gradually rolling out more detailed post analytics on mobile, building on its push for creator insights.

  • Profile Features: Tests continue with expanded profile customisation, including cover images, as the platform experiments with new design elements.

Bluesky Social Updates

  • User Growth: Bluesky continues its momentum and has now passed the 25 million user mark.

  • Trending Topics Expansion: The new trending tab is getting broader visibility, helping users discover popular discussions and boosting community interaction.

Other Platforms

  • Snapchat and Instagram Convergence: Both platforms are doubling down on private sharing, with Snapchat Maps and Instagram’s push to DMs showing how the focus is shifting away from public Stories toward more personal interactions.
