@FroehlichMarcel sso, not massive amounts of people here... does xyz have a different feel because of the mathematicians there? where do the semweb people go?
@pdehaye I can't see the toot to which you are replying, but when it comes to finding people, you might like to try this link:

Finding your first person is hard, but then you can "pull on the thread".
You can also search for hashtags like #SemWeb and similar.
