Good on you, that takes guts. LinkedIn is a giant sucking in your data and attention, so closing it feels like a tiny personal revolt. Xing is far from perfect, but if you need something that actually fits EU rules and DACH networking, it makes sense.
Heads up though, network effects are brutal. Expect fewer international leads and some paywalls for features people take for granted on LinkedIn. Also export any contacts or data you want before it vanishes, and put a simple CV or contact page on your own website so recruiters can still find you without feeding a US platform.
Nice to see someone chipping away at the US dependency list. Keep it up and report back if Xing turns into something workable or just another walled garden.
