Now that we've had some time in beta, we're looking at solidifying our site description.
This is what we've come up with:
This site is for artists, crafters, and hobbyists interested in creating handmade, tangible works.
It gets right to the point! It's for a variety of users, and it's clear that it's about the process of making things (and not, say, art history). "Tangible" means we're generally excluding digital works, but also things such as dance and music.
Let us know what you think!
Our description in the tour page now reads:
Arts & Crafts Stack Exchange is for artists and crafters, from professionals to hobbyists, who are interested in creating handmade, tangible works. It's built and run by you as part of the Stack Exchange network of Q&A sites. With your help, we're working together to build a library of detailed answers to every question about traditional artwork and handmade items.
Which combines the top-rated current answer with some slight changes discussed in the comments.
This change need not be permanent, if community opinion changes.
