Lomographers are good for the analog community in general, since their use of film makes our favorite photographic medium more commercially viable in the long run. Besides that I see little mutual benefit between these two groups, and anyone interested in both is able to join as many forums as one wants to cover the whole range of interests.

Look at this thread if you want to see what happens when APUGs known experts in photo chemistry run into lomographers. Astronomic units can't describe the distances these two worlds are apart.
