Photo by Tim SomeroI've been knocking around 
Flickr for about a year now, but I never really felt plugged into the community.  Flickr is just so big.  However, I recently discovered some cozier communities within Flickr. 
The 
New Hampshire group has about 350 members interested in photographing (or just viewing photos of) the Granite State.   The group is very active.  Many members contribute photos to the group  and there are even a few organized projects.  For example, the 
Cupolas, Steeples & Vanes project is busy capturing some of New Hampshire's unique architectural features.  The New Hampshire group even has a separate blog .  The 
New Hampshire Photo Tour blog highlights the best work in the group.
Even closer to home for me is the 
Souhegan Valley group.  This group has only fourteen members, but I think their photos are very good.
If you appreciate the beauty of New Hampshire, check out all the links above.  If you have another passion -- from 
Architecture, to 
Cows, to the 
Red Sox - try searching all 
the groups on Flickr.   You're bound to find a group that's more your cup of 
tea.
