LinkedIn leads in engagement, while open platforms lag behind.

1Platform Fragmentation Post-Musk Era

Since 2008, Martin Fowler has used social media to announce blog posts. Post-Musk Twitter fragmentation led him to diversify across LinkedIn, X, Mastodon, and Bluesky. Each platform requires manual posting adjustments, though RSS remains his preferred distribution channel. This multi-platform approach allows comparison of engagement metrics across different networks, revealing stark performance differences.

2Engagement Metrics Methodology

Fowler analyzes three key metrics: retweets (sharing intent), likes (approval), and replies (discussion). Instead of averages, he uses strip charts with box plots to show full distributions including medians and quartiles. This approach prevents data distortion from outliers while maintaining visibility of individual post performance. The methodology reveals nuanced platform differences that simple averages would obscure.

3LinkedIn's Clear Dominance

LinkedIn emerges as the clear leader across all engagement metrics. For retweets (Fowler's most valued metric), LinkedIn's median exceeds X's upper quartile. Zoomed-in data shows LinkedIn's engagement edge is substantial, with X a distant second. This performance gap has widened since 2025, with LinkedIn growing while X declined. The data suggests professionals engage more seriously with technical content on LinkedIn.

4Open Platforms Lag Behind

Mastodon and Bluesky show minimal engagement, with their upper quartiles below X's lower quartile. Mastodon slightly outperforms Bluesky, but both generate negligible traffic compared to commercial platforms. Despite generating just 300,000 visits versus Google's 1.7M, LinkedIn drives more referral traffic than all other social platforms combined. Fowler continues using these open platforms due to ideological preference over practical results.

5Year-over-Year Platform Shifts

Comparing 2025 to 2026 data reveals significant platform changes. LinkedIn grew modestly while X declined noticeably. Bluesky's engagement collapsed dramatically, possibly due to network effects favoring established platforms. These trends suggest consolidation toward LinkedIn for professional content, challenging the notion that decentralized platforms can compete with commercial networks for technical audiences.

6Content Distribution Strategy

Fowler now reserves social media primarily for article announcements, moving casual thoughts to 'fragments' posts (his modern link blog). This approach offers more creative freedom and avoids multi-platform posting hassles. RSS remains his preferred consumption method, reflecting a preference for controlled information flow over algorithmic feeds. This strategy maximizes efficiency while minimizing platform dependency.

7Platform Usability Challenges

LinkedIn's forced algorithmic feed makes it unusable for Fowler's preferred reverse-chronological reading. X requires list curation to avoid its 'For You' feed, while Mastodon and Bluesky natively support chronological viewing. These UI differences impact platform utility beyond raw engagement metrics. Fowler's experience highlights the tension between platform design and user needs, particularly for information professionals.

8Implications for Content Creators

The data suggests professionals should prioritize LinkedIn for technical content despite its limitations. Open platforms currently can't match commercial networks' reach, though ideological considerations may justify their use. The analysis underscores that engagement depends on both audience behavior and platform design. Creators must balance practical results with personal preferences when allocating limited distribution efforts.
