@design_RG Yea...you're right...there's a lot of junk there...
But on the other side you can expect to find anyone that might be relevant to you. Not everyone is here....at least for now...:-)
As for the questions, Im all questions get ready. :-) Thanks a lot

@pauloselias Hello and welcome to the Fediverse.
I would prefer if Twitter stayed out of it, as it would bring a lot of junk and problems into fedi.
It has some good things, I have and use accounts there - mostly to follow professional media like the BBC, Guardian, etc.
Enjoy your stay, ask questions if needed!
