Dear friends – today’s the day: Andy’s leaving twitter!. It was so much fun to be here and I will miss part of it. However, this platform also changed so much that it is sometimes hard to recognize any longer. Lot’s of momentum at @bluesky – moving over there. A last thread 🧵

RT @SKhosravani_PhD: I was fortunate to work with my role model @foxmdphd . Thank you for the quality time you created for us, for the big….

Please don't DM me here on Twitter, I am rarely (never) logged in.

Briefly breaking my twitter silence to mention that I am hiring, postdocs, PhDs and admin folks to found a new institute for network stimulation in Cologne, Germany!. More info on the other platform: . Please RT for reach! 🙏🙏

Deep Brain Stimulation starter pack on @bluesky .

RT @netstim_org: Join us on @bluesky! 😀.

RT @leaddbs: We’re also out of here – see you on the bright side! 😀.

That’s all, folks – this time forever … at least here on Twitter :)

Lots of good spirit, block buttons and positivity. Let’s build a better world together!. I have also moved @leaddbs, @stimbrains and @netstim_org and created a @Brain_Circuits handle, over there, too.

So, if you are like me, head over there and see that many of the typical early-adopters like @russpoldrack or @micahgallen are already active and thriving. There are also starter-packs of follows to get you off the ground. The interface is much better, lightweight and clear.

But finally, third, I have always believed that the scientific discourse should be run on a non-commercial platform (e.g. run by the @NIH). Science, in its foundation, has to be free from commercial interests of politics. Bluesky, as a public benefit corporation. is a start.

The recent election results showed that, to some degree, politics have become a basaar in the US – with billionaires pouring in >100 Mio USD (and then get >20 Bn USD in returns the day after) like Elon did.

Second, the leadership of twitter has become extremely biased, politically. By providing quality content on this platform, we support this ideology. I know everyone tries to find excuses, but there is no way of talking yourself out of this.

Multiple reasons: First, it just isn’t the same anymore. Too many cat-videos (I look at them because I love cats and then I get even more cat videos, etc.) By trying to compete with tiktok, twitter really became incompatible with a scientific platform.

I learned a lot here, it was the perfect place to stay up-to-date, I made friends, and I would even say that my twitter presence was to some degree ‘career defining’ for me. So why am I leaving now?

Twitter was like a ‘never ending conference’. Here, you got the ‘bytext’ not mentioned within the publications, summaries, and a scientific community. I am not active on any other social media and mainly used twitter for professional reasons. But it felt like a home.

During my postdoc at @BIDMChealth with @foxmdphd in 2016, I was starting up @leaddbs and saw that @FreeSurferMRI had a twitter account. So I thought: In Rome, do as the Romans do and set up shop with a Lead-DBS handle. Soon, I realized, this was fun and like a …
