There are many reasons I love Flickr. One of the reasons it is great is that photos posted on Flickr are copyrighted, and you can also decide whether you want to allow people to be able to download your pictures or not.
For this reason, there are a lot of both professional and amateur photographers who use the site and post high quality images. Because of this, Flickr is a place that people like journalists and newspaper writers will go to search for images to illustrate articles, travel guides or websites.
In the past few years I have had 3 pictures published, and I got an email yesterday requesting my permission to publish another one.
For an amateur photographer, the recognition feels great.
Here are the pictures I've had published. I don't actually think these are my best photos, but they were what these people were looking for.

This one of Bill Clinton Street in Prishtina, Kosovo was used in a French news article about the unveiling of a statue of Clinton in Prishtina:

This photo from Sirok, Hungary will be published in a German economic journal:
