As a very introverted person who almost borders on agoraphobic I found both of the local maker spaces welcoming and comfortable spaces.
I am also a real nerd/geek sloth who gets excited about things most people do not care one bit about and have no clue about.
The very first time I saw a meeting at one of the local maker spaces, it was almost life changing. For the first time in my life I saw 50 people who were actually like me. I didn't know other people like me even existed.
All I can say is: if you think you might have the slightest interest in a maker space or maker community, go check it out, like the article says, I have found them to be the most welcoming and non judgmental community I have ever had the pleasure to be a part of.
