I finally started blogging about photography and microstock. My blog is in french though ;). My first post on microstock agencies is about Dreamstime since it's my favorite one :)
You can check it out at http://ericcote.squarespace.com and let me know if you like it. You can let comments in the blog articles too, people seems to be shy at the moment (although it's still new).
I update it almost everyday. I'm talking about photography basics but also about advanced notions, microstock, news, etc. I hope people will find it useful (and hopefully will bookmark it or subscribe to the RSS feed).
