Been seeking a good web service to display photography and make it easily available to people for purchase. Through connections with other photographers on Twitter, I found RedBubble.com
Spent a lot of time this weekend sorting through a few thousand images from the last couple of years. RedBubble has a global community and groups of special interest. So far I've contributed to Texas (of course), New York and Italy. The cool thing is my photos made each of those group pages, displayed under "Recent Work". By the time you read this, they may be gone because the work rotates quickly. But it was gratifying to see my photos on those pages and getting at least a few clicks for viewing.
To answer your question: no, I have not yet quit my "day job".
But now I see that all things take time, and if I'd stuck with some projects I started about 9 years ago, I'd be a lot further along now. So, re-starting...
