Finding the different and various Photography groups can be a bit daunting at times. You can look through the tags #photo #photography, look at a few of the post that catch your eye, then look at what other tags they used in their post, or if they have any banners at the end of their post from some of the photo groups.

While not a photo group per say, the tag #wednesdaywalk is a very nice group of social people, the reason for the tag is to get people to go out once a week, take a walk and take some pictures of their walk and share the walk with other followers of the tag. It is run/managed by @tattoodjay. Some of the post can be quite extensive and some of them not so, but all of them are from people looking to share and have fun.

There are a few other various photo challenges/contest out there, that is also a place to sort of meet new users, but when it is a competition the focus of the participants are often for the rewards, not so much the interaction. (This is not true of all the contest, some have a core group that do interact with each other).
