Wow…can’t believe it took me 10 years to get to @pougorg.bsky.social but it delivered in every possible way. So great to see old friends and I haven’t learned that much at a conference in a very long time. ⭐️⭐️⭐️⭐️⭐️

And it’s over, sadly. #poug2025 ended yesterday, and it was a great 10th anniversary event very well organised by the @pougorg.bsky.social team. Well done @luizafrompoland.bsky.social and @ora600pl.bsky.social Looking forward to #poug2026, no idea where it will be, but I will be there.
