I just want let people know, if you have a local community workshop or hacker space, I strongly encourage you to check it out. I am lucky to have two in my area, one of the 8 TechShops around the US and a smaller, more community driven workshop (Maker-Works).
I found both to be amazing resources as far as tools, classes and community support are concerned.
I am one of those very introverted people, I do not go out much at all socially and really avoid going out in general if I can. I am also pretty geeky, programmer, hardware hacker type.
I was amazed at how friendly, accepting, encouraging and similar to myself everyone at these two shops were. I really could not get over it. I went to one of the meetings at the local community hackerspace shop and literally felt like I was in a room full of people very very much like myself for the first time in my life (I'm 45).
I can not say enough good things about these places. I realize my experience is only at two of them, but really, even if there is a 50/50 chance one of them in your area might be as great of an environment as the two in my area, it is really worth it to go check them out.
