As a former student-turned-enthusiast with a really really long history in this space, I am neither an artist nor a craftsman. Am I allowed here?
Arts & Crafts is a Q&A site for artists, craftsmen, amateurs, professionals, students, ex-students, retirees, hobbyists, teachers, designers, scholars, researchers, historians, tinkerers, and other people who have questions about traditional artwork and handmade items.
One of the mistakes of Area 51 is that it asks you to "describe your audience" as a way to define a site — and that typically results in some very long and hollow descriptions that add very little to just having the title on its own. Everyone is invited. We get it. Sites are much easier to explain by <subject> rather than the <title> of the people welcome to use it (usually), so we're trying to get away from bulking up the descriptions in the name of being "all inclusive" unnecessarily.
Don't start futzing with your description now. It got you this far and everything is going really well. We don't create a lot of insular "member only" sites, so I seriously doubt if craft professionals are mulling over their credentials wondering if they will be welcomed to use a site about "Arts & Crafts".
It simply is not necessary.
Besides, the single most important design element of a new site is the questions on the front page ← Aw, crud… I just gave away the surprise ending of a pretty good blog post. Meh, it's a good read anyway. Have a look.
