I think that many quilters now have blogs or some kind of online identity -- even if they aren't making money or selling anything, they may just maintain a blog in order to enter contests or give aways, or quilt alongs, etc.
And if you have a blog name, you may as well use it as a "brand" for your quilts, just for the fun of it. Mine is csQ -- cognitive surplus quilter. I have a small tag I insert on my projects with my csQ logo -- just marks it as my work. I often don't make the whole traditional quilt label on the back, since I document and photograph my quilts and keep the record on my blog, and I give the recipient of gift quilts a tag with the maker information, care directions, and web link.
