I am on a Flickr Pentax site and it is mostly for the fun and enjoyment of fellow Pentaxians and to share our efforts among each other. I am satisfied that there is some learning and improvement in technique and style there, and some gear talk that is helpful, but mostly we enjoy the company of each other. We are not a politically oriented site, and try to avoid conflicts, which we manage very well, and just share our mutual interests. Currently we are having our Fall Squirrel Frenzy, in association with the Nikon Flickr site, and invite any here that are interested to drop in and post a squirrel shot if you have one and want to join the WSSA (Worldwide Squirrel Shooters Association). For serious discussion on gear, technical aspects of photography, and other more serious discussion, Pentax Forums is still the best site on the internet.
Here is where our current Fall Frenzy is taking place.....

I do agree with Flippedgazelle, browsing photos is not only fun it can lead you in new directions, and does not have to be "perfect" to do so.
