The teams that obsess over developer experience compound differently than the ones that don't
Good DevEx means
→ More developers build on your stack
→ More developers means more applications
→ More applications means more users
→ More users means more developer interest
It's a flywheel that starts with the quality of your documentation
The ecosystems that win long term, Ethereum, Solana and eventually others, win partly because building on them is learnable
The ecosystems that fade usually have a "great technology, painful to build on" problem
The best chain is often the one with the best SDKs
X just launched “React with Video” and it’s one of the biggest shifts in how we engage on this platform.
For years, text replies have been the default way to share your thoughts on X. But let’s be honest sometimes words alone don’t capture your real reaction.
Your tone, your energy, your face, your live expression that’s where the real commentary lives.
Guess what, X just fixed that.
You can now respond to ANY post with a full video reaction directly from the repost menu. No third-party app. No editing. No friction. Just hit record and let your thoughts be seen AND heard.
Here’s how to use it:
1.Tap the Repost button on any post
2. Select “React with Video”
3.Choose layouts like Green Screen, Split Screen, or Picture-in-Picture
4.Record your take and share it straight into the conversation
Each layout gives you a different creative angle:
Green Screen - place yourself over the original post as your backdrop
Split Screen - your video side by side with the content you’re reacting to
Picture-in-Picture - overlay yourself on top of the post seamlessly
Is this X’s direct answer to TikTok Duets and YouTube video replies?
For creators, journalists, and commentators this is a game changer. Your audience doesn’t just want to read your opinion anymore.
They want to SEE your reaction. They want your energy. This feature hands you that stage.
Currently live on iOS, Android & Web coming soon.
