These two groups appear to overlap quite a bit and I propose that we merge them into one.
Here are the mission statements for each group:
The popularity and use of DRUPAL has grown by leaps and bounds; thanks to the vibrant community it has developed around it.
The South Bay DRUPAL meetup is another effort in building and strengthening the local Drupal Community.
The South Bay DRUPAL Group is an effort in building and strengthening the vibrant Silicon Valley Drupal Community.
Merging the two groups would include members and posts. Most of the posts in each group have been cross-posted to the other one anyway. I also noticed that one organizer is an organizer of both groups.
Having two groups that serve the same purpose or geographical area can create more work for the organizers in each group and is confusing to new members. Not to mention there are two South Bay regions in California.
