I love Ravelry for many reasons. It's inspiration, it's community, it's a great place to track and show off projects with like minded fiber folks, and it's an excellent tool.
Another thing that I get from it is recognition from peers for a project that was well crafted. I have been asked three times now to have a photos of my projects featured with the pattern page. That little nod means a lot. Almost as much as when a pattern designer compliments me on my interpretation of their pattern.
Obscurity is not a promotional tool.
