I am looking for sites to share my photos, and maybe even sell a few(*). Basically, I have decided that my traditional blog is poorly suited for what is overwhelmingly photo posting with maybe brief comments on some of them. I see that some very good photographers here use 500px, so that is one site I would like to get your opinions of, along with other suggestions. (Links to existing discussions here at LuLa are also welcome!)
* Honestly, any thought of selling is more about ego than revenue; I would also be happy for a site that just lets me know when one of my images is downloaded, perhaps by creating some "no fee license" with each downloader. I promise that the sharing of a few of my snapshots will not undermine any legitimate professional career.
P. S. Is this topic of sharing and selling sites and strategies for using them, big enough to have its own sub-forum, or do us amateurs just call ourselves "professionals" as soon as we contemplate sell images online, and so and use the "Pro Business Discussion"?
